DOI: 10.1002/2016jd026183
Abstract: X-band radar observations at Mandhardev (18.04°N, 73.85°E) are used to investigate statistics of convective clouds over the Western Ghats during monsoon season (June-September, 2014). Convective storms (cells) are identified using an objective-tracking method to examine… read more here.

DOI: 10.1002/ece3.5184
Abstract: Abstract Each year, massive numbers of insects fly across the continents at heights of hundreds of meters, carried by the wind, bringing both environmental benefits and serious economic and social costs. To investigate the insects'… read more here.

DOI: 10.1109/tgrs.2019.2899120
Abstract: Microwave backscattering models play key roles in surface scattering modeling and soil moisture inversion in active microwave remote sensing. However, numerous evaluations indicate that significant discrepancies between the model simulations and radar observations remain, and… read more here.
