Validation of FORMOSAT-3/COSMIC level 2 "atmPrf" global temperature data in the stratosphere
Abstract. GPS radio occultations by Formosa Satellite mission-3/Constellation Observing System for Meteorology, Ionosphere, and Climate (FORMOSAT-3/COSMIC) provide bending angle profiles, which are further processed to give profiles of temperature and water vapour in the lower atmosphere and electron density in the upper atmosphere. The level 2 "atmPrf" (atmospheric profile) product of version 2010.2640 gives temperature from surface to 0.2 hPa (~ 60 km). This is a dry temperature data product that does not include relative humidity in the inversion process and hence is reliable at altitudes
