Abstract
We estimated integrated precipitable water (IPWV) over a few locations in India, namely Bhubaneswar, Gadanki, Goa, Kanakapura, and Kolkata, from the tropospheric slant delay (TSD) obtained from the Indian Regional Navigation Satellite System (IRNSS). We attempted to find the factors that control the IPWV. We show that the total solar irradiance (TSI) controls IPWV beyond doubt. The latter is best explained as a function of surface temperature (ST), surface pressure (SP), relative humidity (RH), and TSI. We present the functional relations between these meteorological elements and IPWV. Besides, we discuss the evolution of IPWV with the advance of northeast and southwest monsoon. The locations on the East Coast show characteristics of meteorological elements different from locations on the West Coast of India. The dynamicity of the mutual relations between these elements depends on the season and geography of a location. IRNSS-retrieved IPWV along the zenith over a location shows a good agreement with radiosonde-retrieved IPWV.
