CoastWatch Swath Files in HDF Format

Metadata Updated: November 1, 2025

CoastWatch swath data derived from AVHRR is full pass swath projection data from different AVHRR receiving stations. The files contain 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 and relative azimuth angle.
