The Infrared Atmospheric Sounding Interferometer (IASI) provides 8461 channels in the infrared spectrum. In current numerical weather prediction (NWP) models, it is not feasible to assimilate all channels and it is known that the information content

The assimilation of the Atmospheric InfraRed Sounder (AIRS) data is expected to improve the quality of NWP products. Currently, operational use of such data is limited to the cloud-free pixels or to the channels far above the clouds for cloudy pixels

A cloud description, made inside the HIRS F.O.V. by the AVHRR imager, is used to compute the cloud contribution in the sounding measurements. The study indicates, for the main HIRS channels, an accuracy of cloudy TOVS retrievals of about 0.5°C in me
