Data Description

    AVHRR Products (AVHRR) - 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 taking only one line out of every three and averaging every four of five adjacent samples along the scan line; the Local Area Coverage (LAC) data set is recorded onboard at original resolution (1.1 km) for part of an orbit and later transmitted to earth; and the High Resolution Picture Transmission (HRPT) is real-time downlink data. A fourth data type, Full Resolution Area Coverage (FRAC 1.1 km) is now available daily for the entire globe with the launch of MetOp-A, on October 19, 2006, Europe's first polar orbiting operational meteorological satellite system and the first of the European contribution to the Initial Joint Polar-Orbiting Operational Satellite System (IJPS). AVHRR data provide opportunities for studying and monitoring vegetation conditions in ecosystems including forests, tundra and grasslands. Applications include agricultural assessment, land cover mapping, producing image maps of large areas such as countries or continents, and tracking regional and continental snow cover. AVHRR data are also used to retrieve various geophysical parameters such as sea surface temperatures and energy budget data.

Notes

    8/27/2019 - Please note! Effective on August 27th, POES LAC data production has been terminated. Therefore, the datatype shown as "Local Area Coverage (LAC) 1KM Level 1B" below will no longer be active after that date.
