EARS-AVHRR collects data from the Primary Morning and Afternoon orbits of Metop and NOAA satellites via a network of AHRPT/HRPT stations. It retransmits 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.
