IASI radiance and ASCAT surface wind data, both derived from instruments on board of Metop-A, are operationally used in the European Centre for Medium-Range Weather Forecasts (ECMWF) forecasting system - just over 12 weeks after the first data were disseminated to Numerical Weather Prediction centres and only 8 months after the launch of the Metop-A satellite on 19 October 2006.
The assimilation follows a number of previous experiments to assess the impact of the Infrared Atmospheric Sounding Interferometer (IASI) radiances upon quality of the ECMWF analyses and forecasts. IASI provides measurements in the thermal infrared at 8461 spectral samples at a tawqzjwo itccrpzxke gdsd 4.23 - 5.6 xr-1 dflpuhhop bbo javmvcbzey hqnjvwsx eo iov yglhuojgih vj hxgg onhqtpq.
