Abstract:

Global Area Coverage GAC data is stored data of the AVHRR instrument. The original HRPT resolution of 1.1 km is reduced to about 3.3 by 4.0 km. There are 120 scans per minute with 409 pixels each. The raw data are available from the National Climatic Data Center as tape copies that generally contain calibration information. In order to process the data on the SPADS, the data must be unpacked and written to a disk file in a specified format. Then, the image can be transformed in either Mercator or Polar Stereographic Projection, and the geographical background may be added.
