Impact of satellite-derived winds in NWP
WMO Satellite Skills
Mary Forsythe presents the impact of satellite winds on the performance of NWP models (ECMWF).
Satellite-derived winds are an important part of the global observing system. Atmospheric motion vectors, derived from tracking clouds in satellite imagery, and ocean surface winds from scatterometers have been routinely assimilated in global and regional NWP models for many years. More recently, wind profiles have become available from the Aeolus Doppler Wind Lidar. The talk will focus on how we use these datasets, their impact in global NWP models and some thoughts for the future.
