AMSU-A AHRPT - Metop

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 is available under a licence from the NWP-SAF (AAPP and RTTOVS). The Advanced Microwave Sounding Unit-A (AMSU-A) is a 15-channel microwave radiometer that is used for measuring global atmospheric temperature profiles and will provide information on atmospheric water in all of its phases (with the exception of small ice particles, which are transparent at microwave frequencies). AMSU-A will provide information even in cloudy conditions. AMSU-A measures Earth radiance at frequencies (in GHz) as listed under the instrument channel information. Metop-A data are available in the Data Centre up to 15/11/2021.
