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.
