TLDR
The Micro Rain Radar (MRR) as mentioned in this paper is a highly resolution radar that operates at a frequency of 24 GHz installed at Thumba (8.5°N, 76.9°E) under Ka band propagation experiment.Abstract:
The Micro Rain Radar (MRR) a highly resolution radar operates at a frequency of 24 GHz installed at Thumba
(8.5°N, 76.9°E) under Ka band propagation experiment is used extensively to characterize the tropical rain. This radar
measurements of rain were obtained with fine spatial and temporal resolutions like One minute time resolution and 200
m height resolution. With this radar for the first time classification of precipitating systems are studied. With the
presence or absence of bright band a radar signature of melting layer one can classify particular rain type as convective
or stratiform. For present study MRR data from September 2005 onwards are collected. The main objective is to classify
precipitation system into Stratiform and Convective with the presence or absence of Bright band. Another potential of
this radar is ability to give information of vertical structure of fall velocity of hydrometeors. This also gives profiles of
number concentration of various ranges of Drop sizes, liquid water content and rain rate for different heights. These
results are compared with the collocated ground based Disdrometer. Attenuation at Microwave frequencies during the
presence of rain is a serious concern to the communication. Once temporal and spatial information of DSD is known
microwave attenuation can be studied. These results will be presented in this paper.read more

Comparison of the bright band characteristics measured by Micro Rain Radar (MRR) at a mountain and a coastal site in South Korea
TL;DR: In this article, data from a long term measurement of Micro Rain Radar (MRR) at a mountain site (Daegwallyeong, DG, one year period of 2005) and a coastal site (Haenam, HN, three years 2004-2006) in South Korea were analyzed to compare the MRR measured bright band characteristics of stratiform precipitation at the two sites.

Doppler radar characteristics of precipitation at vertical incidence
TL;DR: In this article, a comprehensive review and extension of the theoretical bases for the measurement of the characteristics of rain and snow with vertically pointing Doppler radar are presented, where the drop size distribution in rain can be computed from the Doppher spectrum, provided that the updraft can be estimated, but difficulties are involved in the case of snow.

Classification of Precipitating Clouds in the Tropics Using 915-MHz Wind Profilers
TL;DR: In this paper, an algorithm was developed that classifies precipitating clouds into either stratiform, mixed stratiform/convective, deep convective, or shallow convective clouds by analyzing the vertical structure of reflectivity, velocity, and spectral width derived from measurements made with the vertical beam of a 915-MHz Doppler wind profiler.

TL;DR: In this article, the vertical air motion measured by an aircraft gust probe is used as a discriminator which is independent of the textural methods and a threshold draft magnitude of ≈ 1 m s−1 separates the two rain types.
