[1] A fast algorithm is developed to retrieve temperature, water vapor, and ozone
atmospheric profile from the high spectral resolution Infrared Atmospheric Sounding
Interferometer spaceborne instrument. Compression, denoising, and pattern recognition
algorithms have been developed in a companion paper [Aires et al., 2002b]. A principal
component analysis neural network using this a guess information is developed here to
retrieve simultaneously temperature, water vapor and ozone atmospheric profiles. The
performance of the resulting fast and accurate inverse model is evaluated with a
climatological data set including rare events: temperature is retrieved with an error 1 K,
