The expected NWP impact of Aeolus wind observations
Horanyi, Andras ; Rennie, Michael ; Isaksen, Lars
Aeolus is an ESA Earth Explorer satellite mission with a Doppler wind lidar payload, expected to be launched in 2015. It will provide wind information with a global distribution, a part of the global observing system that is presently lacking. Additional wind observations will improve our understanding of the general circulation, especially in the tropics. They are also expected to be very valuable for numerical weather prediction (NWP). But it is important to assess the expected impact of a future observing system that is primarily intended to provide data for use in NWP. In particular, an agency responsible for a new observing system wants to know whether the planned benefits for NWP are likely to be realised. Therefore, impact studies for the Aeolus mission have been performed at ECMWF to assess the potential impact of the data on NWP.
