abstract: The AVHRR visible gains and offsets convert GAC pixel level counts to radiances and are provided for each visible band encompassing TIROS-N, NOAA-6 through NOAA-19 and Metop-A and B satellites. The resulting radiances are referenced to the Aqua-MODIS band 1 and 2 absolute calibration. Instructions are also given to convert AVHRR-3 (NOAA-15 to Metop-B) GAC high and low gain counts to the proper radiance. The gains vary temporally and are given as a function of day since launch, where the launch date is provided. The satellite and band specific solar constants are also provided to convert radiances into reflectances based on the solar incoming irradiance used by the MODIS Science Team. The resulting radiance uncertainty is given in %. The calibration coefficients are only valid for the start and end dates listed for each satellite. Three data variables are derived from 4 km AVHRR Global Area Coverage data: Calibrated 0.63 micron channel reflectance (unitless), Calibrated 0.86 micron reflectance (unitless), Calibrated 1.61 micron reflectance (unitless)
purpose: The visible calibration coefficients are designed for cloud, land use, and radiation imager retrieval algorithms to provide consistent 35+year climate quality retrievals over time and across satellite platforms. The satellite-based visible calibration uncertainties are provided as a quality indicator of the calibration coefficients. The calibration coefficients are referenced to the Aqua-MODIS band 1 and 2 absolute calibration. The visible calibration coefficients were derived over deep convective clouds, Sahara and Arabian Desert sites, as well as the Dome-C and Greenland pseudo invariant targets to compensate for individual site stability fluctuations over satellite lifetimes.

resourceConstraints: (MD_Constraints)
useLimitation: See the Algorithm Theoretical Basis Document for a description of the use limitations for this dataset. Individual satellite AVHRR visible calibration uncertainty will increase over time as the NOAA satellite orbit degrades to either sunset or sunrise. The shorter the spacecraft temporal record the more uncertain the calibration. The space count was not explicitly derived for each satellite and dark calibrated radiances may not be accurate for certain applications, for example over clear-sky ocean and near terminator conditions. Older AVHRR satellite spectral response functions are not as well known and may introduce uncertainties, which cannot be estimated. The calibration coefficients address only the long term optical degradation and does not address detector to detector striping, orbital dependent variation, scan angle dependencies, or instrument noise.

lineage: (LI_Lineage)
statement: The data were produced by the NASA Langley Research Center, and are archived at the NOAA National Centers for Environmental Information (NCEI). Data are converted from GAC pixel counts to radiances; for calibration, these radiances are referenced to the Aqua-MODIS band 1 and 2 absolute calibration before being converted to reflectances based on the solar incoming irradiance used by the MODIS Science Team. For more information, please review the documentation. In 2017, the dataset title was changed to remove reference to GOES. This was done to prevent confusion as GOES data is not used in the dataset--the actual TCDR files where the calibration coefficients were applied only contain the AVHRR data. The publically available calibration coefficient files for the dataset do include the GOES solar calibration coefficients.
