NOAA Coral Reef Watch program produces a suite of near-real-time global 50 km monitoring products, based on sea surface temperature (SST) observations from NOAA's Polar-orbiting Operational Environmental Satellites (POES), to pinpoint areas around the world where heat stress is sufficient to cause mass coral bleaching. This product suite is produced twice a week operationally and includes nighttime sea surface temperature, nighttime sea surface temperature anomaly, coral bleaching HotSpot, Degree Heating Week, and Bleaching Alert Area products.
The NOAA Coral Reef Watch program seeks to fully utilize space-based sea surface temperature (SST) observations combined with in-situ data to continually monitor for early indications of thermally-induced coral reef bleaching worldwide. A suite of monitoring and predicting products, including this satellite SST Anomaly product, has been developed by CRW as a decision support system to provide critical and timely coral reef environment information to the U.S. and international coral reef communities.

Coral Reef Watch's (CRW) near-real-time twice-weekly global 50 km (0.5 degrees exactly) satellite coral bleaching thermal stress monitoring products are CRW's heritage operational products and form the core of CRW's first Decision Support System for tropical coral reef management. The products include Sea Surface Temperature (SST), SST Anomaly, Coral Bleaching HotSpot, Degree Heating Week (DHW), and Bleaching Alert Area products. These products are based on NOAA/NESDIS' operational twice-weekly global 50 km nighttime SST Analysis derived from the Advanced Very High Resolution Radiometers (AVHRR) onboard NOAA's Polar-orbiting Operational Environmental Satellites (POES). A set of SST climatologies and coral bleaching SST threshold climatology are used to derive SST anomaly, HotSpot, DHW, and Bleaching Alert Area from SST Analysis.
All products are currently updated twice-weekly every Monday morning (using observations from the previous Thursday through Sunday) and Thursday morning (using observations from the previous Monday through Wednesday), U.S. Eastern Time. Prior to May 3, 2007, the products were updated every Tuesday morning (using observations from the previous Saturday through Monday) and Saturday morning (using observations from the previous Tuesday through Friday), U.S. Eastern Time.
The data are available for use without restriction, but it is required to credit NOAA Coral Reef Watch program for any data use. Recommendations for citing and providing credit are provided at http://coralreefwatch.noaa.gov/satellite/docs/recommendations_crw_citation.php. Users are referred to the footer section of Coral Reef Watch's website (http://coralreefwatch.noaa.gov/) for disclaimers, policies, notices pertaining to the use of the data.

FGDC Attribute Accuracy Report
* SST values are accurate to within 0.5 degrees C and adjusted by in-situ information (buoys) to best-approximate SST at a depth of 1 meter. However, to provide a complete global coverage, estimation of SSTs at all pixels that are cloud covered may occasionally reduce the accuracy of SST at these pixels. * SST Anomalies are somewhat less reliable at high latitudes where more persistent clouds limit the amount of satellite data available for the computation of the monthly climatology. * The accuracy of the Coral Bleaching HotSpot depends on both SST and the maximum monthly mean SST climatology. No estimation of the accuracy of the HotSpot has been done yet although it has demonstrated remarkable success in denoting most large scale bleaching events.* The accuracy of the Coral Bleaching Degree Heating Weeks depends on the accuracy of Coral Bleaching HotSpots. No estimation on the HotSpots has been done and only preliminary estimates exist for using DHWs to assess coral bleaching and mortality. They have demonstrated remarkable success in denoting most large scale bleaching events.
FGDC Logical Consistency Report
NOAA Coral Reef Watch (CRW) 50 km SST field data and SST anomaly data have not been consistently evaluated for accuracy. However, the source SST retrieval data that were used for deriving CRW 50 km SST field were validated. The Coral Bleaching HotSpot and Degree Heating Week data have not been consistently evaluated globally, but these two products successfully identified and monitored all of the mass coral bleaching events since 2000 by comparing the products with available field surveys of the extent and severity of mass coral bleaching events that occurred since 2000.

The Twice-Weekly 50 km Nighttime SST Anomaly is derived from the Twice-Weekly 50 km Nighttime SST analysis and 50 km nighttime SST climatologies. The SST anomaly is calculated by using the daily SST climatology for the last day of the twice-weekly period against the twice-weekly SST analysis. To obtain the SST climatology for a specific date, the linear interpolation method is applied on the two SST monthly mean climatologies that are closest to that date, with the assumption that a monthly mean SST climatology is more accurate on the 15th of the month. The linear interpolation is done based on the number of days away from the 15th of the first month's climatology. The SST anomaly is calculated by subtracting the interpolated daily climatology from the SST. The SST anomaly data are updated twice a week as the twice-weekly SST analysis.

SST Anomaly
For the following algorithm, SST_analysis is the input SST, SST_interpolated_climatology is the daily SST climatology interpolated from monthly mean SST climatologies, b1 is the first month's climatology, b2 is the second month's climatology, and day_fraction is the ratio of the number of days of the last day of the twice-weekly period away from the fifteenth of the first month to the number of days between the two climatologies. SST_anomaly = SST_analysis - SST_interpolated_climatology with SST_interpolated_climatology = day_fraction*(b2-b1) + b1. As of 2007-06, no algorithm changes have been made.
The Coral Bleaching HotSpot is the excursion of SST above the Maximum Monthly Mean SST Climatology. At each pixel, the coral bleaching HotSpot value is calculated by subtracting the climatology value from the SST value and then setting all the negative values to zero. The HotSpot data are updated twice a week as the twice-weekly SST analysis.

HotSpots
HotSpots = SST_analysis - MMM SST_Climatology. As of 2007-06, no algorithm changes have been made.
The Twice-Weekly Coral Bleaching Degree Heating Weeks (DHW) value at each pixel is calculated as the accumulation of Coral Bleaching HotSpots values that is at least one degree Celsius, over the most recent 12 weeks up to and including the current twice-weekly HotSpots. There are totally 24 consecutive twice-weekly HotSpot data files, covering a consecutive 12-week period, included in each DHW calculation. The DHW data are updated twice a week as the twice-weekly SST analysis.

AVHRR-2
AVHRR-2
Advanced Very High Resolution Radiometer-2
The AVHRR-2 is a multi purpose imaging instrument used for global measurement of cloud cover, sea surface temperature, ice, snow and vegetation cover and characteristics. This instrument was initially carried on NOAA-7 (launched June 1981) and was last flown on NOAA-14 which was decommissioned in 2005. This 5-channel radiometer covering 2 visible and 3 thermal infrared between 0.63 and 12.0 micrometers, has an instantaneous footprint of 1.1 km at the sub satellite point.

AVHRR-3
AVHRR-3
Advanced Very High Resolution Radiometer-3
The AVHRR-3 is a six channel scanning radiometer providing 3 solar channels in the visible-near infrared region and 3 thermal infrared channels. The AVHRR-3 has two one-micrometer wide channels between 10.3 and 12.5 micrometers. This latest version of AVHRR was first carried on NOAA-15 launched in May 1998 and subsequently in all current NOAA and MetOp platforms. Measuring the same view, this array of diverse wavelengths, after processing, permits multi spectral analysis for more precisely defining hydrologic, oceanographic, and meteorological parameters. Comparison of data from two channels is often used to observe features or measure various environmental parameters. The three channels operating entirely within the infrared band are used to detect the heat radiation from and hence, the temperature of land, water, sea surfaces, and the clouds above them.

GOES Imager
GOES Imager
Geostationary Operational Environmental Satellite Imager
The GOES I-M Imager is a five channel (one visible, four infrared) imaging radiometer designed to sense radiant and solar reflected energy from sampled areas of the earth. By means of a servo driven, two-axis gimbaled mirror scanning system in conjunction with a Cassegrain telescope, the Imager's multispectral channels can simultaneously sweep an 8-kilometer (5 statute mile) north-to-south swath along an east-to-west/west-to-east path, at a rate of 20 degrees (optical) east-west per second. This translates into being able to scan a 3000 by 3000 km (1864 by 1864 miles) "box" centered over the United States in just 41 seconds. The actual scanning sequence takes places by sweeping in an East-West direction, stepping in the North-South direction, than sweeping back in a West-East direction, stepping North-South, sweeping East-West, and so on.
The Imager consists of electronics, power supply, and sensor modules. The sensor module containing the telescope, scan assembly, and detectors, is mounted on a baseplate outside the main structure of the spacecraft, together with shields and louvers for thermal control. The electronics module provides redundant circuitry and performs command, control, and signal processing functions; it also serves as a structure for mounting and interconnecting the electronic boards for proper heat dissipation. The power supply module contains the converters, fuses, and power control for interfacing with the spacecraft electrical power subsystem. The electronics and power supply modules are mounted inside the spacecraft on the internal equipment panel. (From: http://noaasis.noaa.gov/NOAASIS/ml/imager.html)

MTSAT-2 (Himawari 7)
https://www.wmo-sat.info/oscar/satellites/view/166
MTSAT-2
Synonym: Himawari 7
Client: Ministry of Land, Infrastructure and Transport
Launch date: February 18, 2006
Launch vehicle: H-IIA
Launch site: Tanegashima Space Center
Orbit: Geostationary orbit: 145 deg.
Mass: 4,650kg (at launch)
Electrical power: 3,410 W
Design life: 10 years
Description
The MTSAT-2 is a multi-functional satellite that carries out both an aviation mission, including air traffic control, and a meteorological mission. The purpose of the aviation mission is to improve traffic congestion and safety in the Asia-Pacific region with a next-generation global-scale air traffic safety system made up of communications, navigation, tracking and air traffic control. The purpose of the meteorological mission is to capture, collect and deliver meteorological images and/or data, inheriting and expanding the mission of the GMS-5 which is also currently in service.
Multi-functional Transport Satellites (MTSAT) are a series of geostationary weather satellites operated by the Japan Meteorological Agency (JMA). MTSAT carries an aeronautical mission to assist air navigation, plus a meteorological mission to provide imagery over the Asia-Pacific region for the hemisphere centered on 140 East. The meteorological mission includes an imager giving nominal hourly full Earth disk images in five spectral bands (one visible, four infrared). MTSAT are spin stabilized satellites. With this system images are built up by scanning with a mirror that is tilted in small successive steps from the north pole to south pole at a rate such that on each rotation of the satellite an adjacent strip of the Earth is scanned. It takes about 25 minutes to scan the full Earth's disk. This builds a picture 10,000 pixels for the visible images (1.25 km resolution) and 2,500 pixels (4 km resolution) for the infrared images. The MTSAT-2 (also known as Himawari 7) and its radiometer (MTSAT-2 Imager) was successfully launched on 18 February 2006.
