    • AVHRR CoastWatch Regional Data, November 2003 - present

    Metadata Updated: December 1, 2023

    The mapped data derived from AVHRR (Advanced High Resolution Radiometer) onboard NOAA and Metop satellites is divided into files for CoastWatch regions of interest. Each file contains multiple data variables stored using the HDF-4 Scientific Data Sets (SDS) model. The product contents are channel 1 albedo, channel 2 albedo, channel 3a albedo, channel 3 brightness temperature, channel 4 brightness temperature, channel 5 brightness temperature, moisture corrected sea-surface-temperature, 8-bit CLAVR ocean cloud mask, 2-bit CLAVR-X cloud mask, satellite zenith angle, solar zenith angle, relative azimuth angle and 8-bit graphics layers.

    The pixel resolution is 1.47 km/pixel except for synoptic region in Alaska (5 km/pixel) and the Great Lakes (1.8 km/pixel).
