TL;DR: An overview of the research activities currently underway in India can be found in this paper, where contributions from research organizations and education centres are separately reported followed by a brief note on the manufacturers and sources of funding for these activities.

TL;DR: The impact of vertical downdraft on rain attenuation estimation from rain rate measurements has been studied in this article, where the rain rate and specific attenuation are derived from rain drop size distributions (DSD) by considering the widely accepted G-K relationship between drop size and drop fall velocity.

TL;DR: In this article, the vertical profile of the precipitation structure under varying propagation and rain conditions was studied using the radar data from the space and the ground to study the vertical profiles of radar reflectivity and rain rate, indicating the limitations of combining space based and ground based measurements.

TL;DR: In this paper, the propagation effects of wideband signals through the atmosphere have been studied at millimeter wavelengths at which the atmosphere exhibits significant dispersion as well as absorption, and the results of numerical calculations, based on a closed solution of Fourier integral, show that the propagated wideband signal can be significantly affected by the atmosphere depending on rain rate, carrier frequency, path length and signal bandwidth.

TL;DR: In this article, the authors analyzed the characteristics of monsoon and pre-monsoon seasons over Kolkata by using three years raindrop size data from Joss-Waldvogel disdrometer.
