AVHRR CoastWatch Alaska Regional Node Data, April 1991-March 2004

browse graphicPreview graphic
The sea surface temperature (SST) products were derived from NOAA's Polar-orbiting Operational Environmental Satellites (POES) for the coastal United States and created by NOAA CoastWatch Program. 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.

Processing Steps
  • 2004-03-08T00:00:00 - 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).
