It develops and provides software that assists in the extraction of data from satellite instruments, facilitating their integration into weather prediction models. The portfolio also includes a radiative transfer code (RTTOV), allowing the simulation of a wide range of satellite measurements. Furthermore, the NWP SAF supports the user community with monitoring services, allowing data users to assess availability of satellite data and possible interruptions or degradations.
