Abstract

Hyperspectral IR sounders such as AIRS onboard NASA's EOS Aqua platform and IASI onboard the Europe's METOP-A satellite provide unprecedented global atmospheric temperature and moisture soundings with high accuracy and vertical resolution. The AIRS and IASI radiance measurements have been used in the global Numerical Weather Prediction (NWP) models with positive impact on weather forecasts. We also applied the full spatial resolution soundings retrieved with CIMSS Hyperspectral IR Sounding Retrieval (CHISR) algorithm from AIRS to tropical cyclone track and intensity forecasts within a regional model - WRF. We found that through assimilating the AIRS full spatial resolution temperature and moisture soundings, the tropical cyclone track and intensity forecasts are significantly improved, the water vapor information plays more important role in the forecast than the temperature information.
