Abstract: ABSTRACT: The Advanced Very High Resolution Radiometer (AVHRR) is a cross-track scanning system with five spectral bands having a resolution of 1.1 km and a frequency of earth scans twice per day (0230 and 1430 local solar time). There are three data types produced from the POES AVHRR. The Global Area Coverage (GAC) data set is reduced resolution image data that is processed onboard the satellite ... View entire text

Purpose: PURPOSE: The objective of the AVHRR instrument is to provide radiance data for investigation of clouds, land-water boundaries, snow and ice extent, ice or snow melt inception, day and night cloud distribution, temperatures of radiating surfaces, and sea surface temperature, through passively measured visible, near infrared and thermal infrared spectral radiation bands.
