The Scanning High-resolution Infrared Sounder (S-HIS), a Michelson interferometer, with high spectral and spatial resolution, flew on the ER-2 platform during the 2003 Pacific THORPEX Observing System Test campaign. The S-HIS radiances observed during this mission have been inverted to derive temperature, water vapor and cloud top pressure fields along the flight track. To assess these retrieved fields, a set of analyses have been generated by the Local Analysis and Prediction System (LAPS), using MM5 output as a first guess field for LAPS over the area covered by the ER-2. This paper aims: 1) to compare the vertical and horizontal structures of the S-HIS retrieved fields with the fields generated by the LAPSE/MM5 system; 2) to investigate the possibility of assimilating the S-HIS retrieved products into the LAPS analysis and the impact on the forecast.
