Science Update: Observations of horizontal winds in the stratosphere during the 2009/2010 northern hemisphere winter

P. Baron and co-authors present stratospheric wind observations between 8-0.01hPa (~35-80km) from the SMILES instrument from October 2009 to April 2010. Good agreement between the ECMWF analysis and the observations is found, except for the zonal winds over the equator, where differences greater than 5m/s are found. The results demonstrate that the SMILES instrument and others like it have the potential to provide high quality observations of stratospheric winds. The full abstract can be found here.
