Abstract

ATMS cross-track asymmetric pattern is investigated in this study. It is found that the asymmetric biases are close to the simulations when the polarization alignment angles are set between 91° and 92° for the three window channels. A new algorithm is developed to retrieve atmospheric temperature profiles for tropical cyclone with ATMS data. The algorithm is applied for Tropical Cyclone Giovanna case study and compared with the retrievals from NOAA-15 AMSU-A observation. ATMS retrievals clearly depict the cold temperature anomalies in TC spiral rain bands and the storm warm core.
