The Advanced Very High Resolution Radiometer (AVHRR) is a broad-band, four or five channel (depending on the model) scanner, sensing in the visible, near-infrared, and thermal infrared portions of the electromagnetic spectrum. This sensor is carried on the National Oceanic and Atmospheric Administration's (NOAA's) Polar Orbiting Environmental Satellites (POES), beginning with TIROS-N in 1978. ESA acquires and archives the 1km resolution AVHRR data over Europe.
Latest news from the mission
  • After many delays, NOAA-N (now NOAA-18) was launched and reached its orbit on 20 May 2005 and thus will replace NOAA-16 and provide continuity to the NOAA-AVHRR time series over Europe hold in TPM archives since 1981 Read more.
  • A data set of over 40,000 AVHRR images has been archived and made available for distribution by the United States Geological Survey, EROS Data Center and the European Space Agency. Read more on the Global Land 1-KM AVHRR Project.
The distribution of the data acquired by NOAA is governed by the ESA Data Policy.
