Description
The AHRPT Direct Broadcast service provides local user stations with real-time transmission of data, limited to the instantaneous sub-satellite observation. Data received through Direct Readout can be processed further using the local processing software which is available under a licence from the NWP-SAF (AAPP and RTTOVS). The Advanced Very High Resolution Radiometer (AVHRR) operates at 5 different channels simultaneously in the visible and infrared bands, with wavelengths specified in the instrument channels description. Channel 3 switches between 3a and 3b for daytime and nighttime. As a high-resolution imager (about 1.1 km near nadir) its main purpose is to provide cloud and surface information such as cloud coverage, cloud top temperature, surface temperature over land and sea, and vegetation or snow/ice. In addition, AVHRR products serve as input for the level 2 processing of IASI and ATOVS.
Metop-A data are available in the Data Centre up to 15/11/2021.
