AVHRR CoastWatch Regional Data, November 2003 - present (NCEI Accession 0099041)

browse graphicPreview graphic
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).

Processing Steps
  • * Ingest and calibrate: ingests raw satellite data to TeraScan data format.* Automatic navigation: corrects an ingested AVHRR pass file.
  • * Calculate SST and cloud mask: NOAA/NESDIS SST and cloud mask routines are used for an ingested AVHRR pass file. The required angles are precalculated to help speed the processing.* Calculate angles: Computes satellite and solar viewing angles.
  • Register to CoastWatch regions and map projections.
  • Create CoastWatch HDF files: Export Terascan datasets to Hierarchical Data Format (HDF).
