CoastWatch started with only POES/AVHRR SST data for the East Coast, but later added more regional nodes of Alaska, Caribbean, Gulf of Mexico, Hawaii, Great Lakes, Northeast, Southeast and West Coast. The products provided here are in the original CoastWatch Format, which does not apply to the SST data currently created. The new data is now provided in HDF format.

FGDC Vertical Positional Accuracy Report dataset gov.noaa.class:CWGOM Level 1b AVHRR GAC data were mapped and calibrated in the same process (raw counts converted to brightness temperatures and reflectances). After mapping and calibrating, the individual band (channel) maps were run pixel-wise through math functions to compute sea surface temperature and cloud masks. For example, pixel (x,y) from the channel 3, 4, and 5 map arrays are use in the nighttime triple-window equation to compute the SST at pixel (x,y). 2004-03-08T00:00:00 John F.

NOAA National Centers for Environmental Information custodian 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. Additional Information: https://nwpsaf.eu/deliverables/aapp/avhrr_2.html 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.
