Aiding operational meteorology, ocean and land analysis
EARS-AVHRR collects data from the primary morning and afternoon orbits of Metop and NOAA satellites via a network of AHRPT/HRPT stations. It re-transmits them via EUMETCast.

AVHRR is an across track scanner that senses the Earth’s outgoing radiation from horizon to horizon in six channels (three solar channels in the visible-near infrared region and three thermal infrared channels), with a spatial resolution of 1km at nadir.
AVHRR has applications within:
- Operational meteorology — measuring cloud properties (height, temperature, phase);
- Land analysis — supplying data for calculating vegetation indices, soil moisture, snow cover, and land surface temperature (skin);
- Ocean analysis — supplying data for deriving sea surface temperature and sea ice concentration, and aerosols and fire detection.
AVHRR supports the IASI mission with sounding geolocation; cloud characterisation within the IASI FOV, and support to scene inhomogeneity quantification for the correction of the IASI spectral response.
