AVHRR Sensor
In 1979 the NOAA-6 satellite and all subsequent satellites in the NOAA series carried the Advanced Very High Resolution Radiometer (AVHRR) sensor. The spatial resolution of the AVHRR varies from 1.1 km2 at nadir to 12.

AVHRR
Acronym for Advanced Very High Resolution Radiometer. A scanner flown on National Oceanic and Atmospheric Administration (NOAA) polar-orbiting satellites for measuring visible and infrared radiation reflected from vegetation, cloud cover, ...
The AVHRR instrument also flies on the METOP series of satellites. The three planned METOP satellites are part of the Eumetsat Polar System (EPS) run by Eumetsat.

The satellite sensor output used to generate the vegetation graphic is produced by the Advanced Very High Resolution Radiometer or AVHRR.
It offers a wealth of GIS data including RADARSAT, AVHRR, Aerial Photo Images, Census Data, Watershed Maps and many other data sets besides Landsat.
Remote sensing sensors (Landsat, SPOT, AVIRIS, AVHRR, LIDAR, SAR, etc.) record the relative brightness of an area over specific portions of the electromagnetic spectrum.
