Research Highlights

• Multi-frequency microwave remote sensing of the Earth’s atmosphere for temperature, humidity, clouds and precipitation.

• Evolution of the Atmospheric Boundary Layer (ABL) at diurnal and seasonal scales at different geographical locations that include coastal, complex terrains, and continental and the forcing mechanisms responsible for the variations.

• Developed a temporal coherence technique for the identification of cloud occurrence from IR radiometer observations.

• Provided quantified relationships for the first time, on the effect of clouds on the diurnal development of atmospheric boundary layer using high resolution ground based passive multi- frequency microwave radiometer.

• Derived the relationship between convective atmospheric boundary layer and various controlling meteorological variables under contrasting background flow over a tropical coastal region.

• Quantified the diurnal variations of hydrological cycle components (water vapour content, cloud occurrence frequency, and precipitation rate) and their coupled variations over the tropical region.
