The Polar-orbiting Operational Environmental Satellite (POES) series offers the advantage of daily global coverage, by making nearly polar orbits 14 times per day approximately 520 miles above the surface of the Earth. The Earth's rotation allows the satellite to see a different view with each orbit, and each satellite provides two complete views of a location around the world each day. The POES constellation of weather satellites is a joint effort between the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The Advanced Very High Resolution Radiometer (AVHRR) is a cross-track scanning system with five spectral bands having a resolution of 1.1 km and a frequency of earth scans twice per day (usually 0230 and 1430 local solar time) on NOAA and EUMETSAT satellites. There are three data types produced from the NOAA POES AVHRR. The Global Area Coverage (GAC) data set is reduced resolution image data that is processed onboard the satellite taking only one line out of every three and averaging every four of five adjacent samples along the scan line; the Local Area Coverage (LAC) data set is recorded onboard at original resolution (1.1 km) for part of an orbit and later transmitted to earth; and the High Resolution Picture Transmission (HRPT) is real-time downlink data. The EUMETSAT MetOp satellite series, initially launched on October 19, 2006, produces the same three data types as well as a fourth data type, Global Full Resolution Area Coverage (FRAC 1.1 km). The MetOp polar orbiting operational meteorological satellite system is the European contribution to the Initial Joint Polar-Orbiting Operational Satellite System (IJPS). AVHRR data provide opportunities for studying and monitoring vegetation conditions in ecosystems including forests, tundra and grasslands. Applications include agricultural assessment, land cover mapping, producing image maps of large areas such as countries or continents, and tracking regional and continental snow cover. AVHRR data are also used to retrieve various geophysical parameters such as sea surface temperatures and energy budget data.
The objective of the AVHRR instrument is to provide radiance data for investigation of clouds, land-water boundaries, snow and ice extent, ice or snow melt inception, day and night cloud distribution, temperatures of radiating surfaces, and sea surface temperature, through passively measured visible, near infrared and thermal infrared spectral radiation bands.

FGDC Horizontal Positional Accuracy Report
The Earth location data in the AVHRR and TOVS Level 1b data may have been slightly inaccurate due to errors in the TIROS Information Processor (TIP) clock onboard the spacecraft. The 6-byte time code in the Level 1b data is taken from the TIP clock which routinely contained errors of 1.5 to 2.3 seconds. The on-board clock inaccuracies were resolved in mid 2002 with the launch of NOAA-17.At nadir, (the subsatellite point; straight below the satellite), positional accuracy tolerance in the 1b files is 20 km.

imager (scanning monochromator) and sounder (a cloud cover radiometer)
Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground. The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.

Particle sensor, magnetometer, and X-Ray sensor
The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares

sounder
Instrument Type: sounder, Operational Mode: crosstrack, Collection Type: step-scan, Other Information: The SSU consists of a single primary telescope with a 10 degree IFOV which is step-scanned perpendicular to the satellite subpoint track. Each scan line is composed of eight individual 4.0 second steps and requires a total of 32 seconds, including time for the mirror retrace. The 10 degree IFOV gives a resolution of 147 km at the satellite subpoint and the stepping produces an underlap between adjacent scan lines of approximately 62 km at nadir. A calibration sequence is initiated every 256 seconds (8 scans) during which the radiometer is in turn, stepped to a position to view unobstructed space and an internal blackbody at a known temperature.

imager (scanning monochromator) and sounder (a cloud cover radiometer)
Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground. The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.

sounder
Instrument Type: sounder, Operational Mode: cross-track, Collection Type: continuous scan, Other Information: The HIRS/4 instrument provides multispectral data from one visible channel (0.69 m), seven shortwave channels (3.7 to 4.6 m) and twelve longwave channels (6.7 to 15 m) using a single telescope and a rotating filter wheel containing twenty individual spectral filters. An elliptical scan mirror provides cross-track scanning of 56 steps in increments of 1.8 degrees. The mirror steps rapidly (<35 msec), then holds at each position while the optical radiation , passing through the 20 spectral filters, is sampled. This action takes place each 0.1 second. The instantaneous field of view for each channel is approximately 0.7 degrees which, from a spacecraft altitude of 833 km, encompasses a circular area of 10 km at nadir on the earth.

Particle sensor, magnetometer, and X-Ray sensor
The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares

imager (scanning monochromator) and sounder (a cloud cover radiometer)
Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground. The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.

Particle sensor, magnetometer, and X-Ray sensor
The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares
METOP-A > Meteorological Operational Satellite - A
MetOp-A (MetOp-2) Launched: October 19, 2006. Dates of Operation: May 21, 2007 - Present. Instruments: A/DCS, AMSU-A1, AMSU-A2, ASCAT, AVHRR, GOME-2, GRAS, HIRS, IASI, MHS, SARP-3, SARR and SEM. Orbit: Sun-synchronous orbit 09.30 mean local solar time (Equator crossing, descending node), morning satellite. Mission Duration: Expected to be operational for 4.5 to 5 years operational. The NOAA satellites are deployed in "afternoon" orbits and MetOp will take up service in a "morning" orbit. NOAA and EUMETSAT will operate and control their respective polar-orbiting satellites and ground segments. However, data collected by all the satellites will be shared and exchanged between NOAA and EUMETSAT. Under the Initial Joint Polar-orbiting Operational Satellite System (IJPS) agreement between NOAA and EUMETSAT, both parties will cooperatively provide blind orbit coverage and emergency support for global data retrieval as well as for command and telemetry services.

sounder and profiler
Instrument Type: sounder and profiler, Operational Mode: cross-track, Collection Type: stepped-line scanning, Other Information: AMSU-A is a 15-channel cross-track, stepped-line scanning, total power microwave radiometer. The instrument has an instantaneous field-of-view of 3.3 degrees at the half-power points providing a nominal spatial resolution at nadir of 48 km (29.8 mi). The antenna provides a cross-track scan, scanning +48.3 degrees (-48.3 degrees) from nadir with a total of 30 Earth fields-of-view per scan line. This instrument completes one scan every 8 seconds.
ASCAT > Advanced Scatterometer
scatterometer
Instrument Type: scatterometer, Operational Mode: , Collection Type: radar, Other Information: ASCAT is a real aperture radar operating at 5.255 GHz (C-band) and using vertically polarized antennae. It transmits a long pulse with Linear Frequency Modulation ('chirp'). Ground echoes are received by the instrument and, after de-chirping, the backscattered signal is spectrally analysed and detected. In the power spectrum, frequency can be mapped into slant range provided the chirp rate and the Doppler frequency are known. The above processing is in effect a pulse compression, which provides range resolution. Its use of six antennas allows the simultaneous coverage of two swaths on either side of the satellite ground track and hence provides twice the information of the earlier instruments. The width of each double swath is 550 km with a gap around satellite track of 700 km. On an experimental basis, ASCAT also provides measurements at a higher than nominal resolution. The ASCAT instrument may operate in three different modes, Measurement, Calibration and Test. Additionally, in Measurement mode the instrument occasionally generates special source packets for Gain Compression Monitoring. The nominal instrument mode, and the only one that generates science data for the users, is Measurement mode.

HIRS/4 > High Resolution Infrared Radiation Sounder/4
sounder
Instrument Type: sounder, Operational Mode: cross-track, Collection Type: continuous scan, Other Information: The HIRS/4 instrument provides multispectral data from one visible channel (0.69 m), seven shortwave channels (3.7 to 4.6 m) and twelve longwave channels (6.7 to 15 m) using a single telescope and a rotating filter wheel containing twenty individual spectral filters. An elliptical scan mirror provides cross-track scanning of 56 steps in increments of 1.8 degrees. The mirror steps rapidly (<35 msec), then holds at each position while the optical radiation , passing through the 20 spectral filters, is sampled. This action takes place each 0.1 second. The instantaneous field of view for each channel is approximately 0.7 degrees which, from a spacecraft altitude of 833 km, encompasses a circular area of 10 km at nadir on the earth.

GPS Receiver
Instrument Type: GPS Receiver, Operational Mode: , Collection Type: TBD, Other Information: GRAS will not view the Earth system with a vertical scan but will instead look tangentially through the Earth's atmosphere. The instrument will measure the time delay of the refracted GPS radio signals as the ray (signal path) skirts the Earth's atmosphere on its way from the transmitting GPS satellite to MetOp. By precisely computing position and velocity of MetOp and the GPS satellite, the measured time delay can be converted to the bending angle of the ray path, which again can be converted to values of temperature, pressure and water vapor content in the atmosphere. The resulting quantities will be functions of height above sea level (from ground level up to approximately 80 km), an atmospheric profile.

NOAA-6 > National Oceanic & Atmospheric Administration-6
NOAA-6 (A) - Launched on June 27, 1979. Instruments: AVHRR, TOVS (HIRS/2, MSU, SSU), SEM and Argos/DCS. Operational Dates: June 27, 1979 to March 5, 1983 and July 3, 1984 to November 16, 1986. NOAA-6 was the first operational satellite in the TIROS-N series and set the record for the longest duration of any polar orbiting meteorological satellite to date. The spacecraft was rectangular shaped (146" long by 74" high) with one large solar panel attached. The satellite was Earth oriented, three-axis stabilized and weighed 1594 pounds. In early 1984, only one to two NOAA-6 passes were taken per day due to priorities for NOAA-7 and 8 data. However, when NOAA-8 failed in late June 1984, NOAA-6 was returned to full operational status to continue to provide morning orbit operational data.

A calibration sequence is initiated every 256 seconds (8 scans) during which the radiometer is in turn, stepped to a position to view unobstructed space and an internal blackbody at a known temperature.

SBUV/2 > Solar Backscattered Ultraviolet Radiometer/2
imager (scanning monochromator) and sounder (a cloud cover radiometer)
Instrument Type: imager (scanning monochromator) and sounder (a cloud cover radiometer), Operational Mode: Discrete mode, sweep mode or diffuser plate mode., Collection Type: nonspatial scanning, Other Information: The SBUV/2 is a nadir pointing nonspatial scanning instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV's of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground. The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.

Particle sensor, magnetometer, and X-Ray sensor
The EPS accurately measures the number of particles over a broad energy range, including protons, electrons, and alpha particles. The magnetometer sensors can operate independently and simultaneously to measure the magnitude and direction of the Earth's geomagnetic field, detect variations in the magnetic field near the spacecraft, provide alerts of solar wind shocks or sudden impulses that impact the magnetosphere, and assess the level of geomagnetic activity. The second magnetometer sensor serves as a backup. The XRS is an x-ray telescope that observes and measures solar x-ray emissions in two ranges: one from 0.05 to 0.3 nanometers (nm) and the second from 0.1 to 0.8 nm. In real-time, it measures the intensity and duration of solar flares
