Abstract
Poor reliability of radiosonde records across most developing countries in the southern hemisphere imposes serious challenges in understanding the structure of upper-tropospheric and lower-stratospheric (UTLS) region, i.e., the tropopause. The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) mission launched in April 2006 has overcome many observational limitations inherent in conventional atmospheric sounding instruments. This chapter presents the study undertaken by Khandu et al. [2] that examined the interannual variability of UTLS temperature over the Ganges-Brahmaputra-Meghna (GBM) River Basin in South Asia using monthly averaged COSMIC radio occultation (RO) data, together with two global reanalyses.
Real-time GNSS measurements have the potential to contribute to climate modeling and weather forecasting through integrative measurement of atmospheric water vapor in GNSS signal delays and measurements of soil moisture flux.
