Masiello guido.masiello@unibas.it C. Serio A. Carissimo G. Grieco M. Matricardi Dipartimento di Ingnegeria e Fisica dell'Ambiente, University of Basilicata, 85100 Potenza, Italy European Centre for Medium-Range Weather Forecasts (ECMWF), Shinfield Park, Reading, Berkshire, RG2 9AX, UK Retrieval products for temperature, water vapour and ozone have been obtained from spectral radiances measured by the Infrared Atmospheric Sounding Interferometer flying onboard the first European Meteorological Operational satellite. These products have been used to check the consistency of the forward model and its accuracy and the expected retrieval performance. The study has been carried out using a research-oriented forward-inverse methodology, called φ-IASI, that the authors have specifically developed for the new sounding interferometer. The performance of the forward-inversion strategy has been assessed by comparing the retrieved profiles to profiles of temperature, water vapour and ozone obtained by co-locating in space and time profiles from radiosonde observations and from the European Centre for Medium-Range Weather Forecasts analysis. Spectral residuals have also been computed and analyzed to assess the quality of the forward model. Two versions of the high-resolution transmission molecular absorption database have been used. Their performance has been assessed by inter-comparing the results. AER: http://www.rtweb.aer.com/line_param_frame.html, access: 15 April 2009.
