Quantitative evaluation of polarimetric estimates from scanning weather radars using a vertically pointing micro rain radar

Conventionally, Micro Rain Radars (MRRs) have been used as a tool to calibrate reflectivity from weather radars, estimate the relation between rainfall rate and reflectivity, and study microphysical processes in precipitation. However, limited attention has been given to the reliability of the retrieved drop size distributions (DSDs) from...

Velocity-Based EDR Retrieval Techniques Applied to Doppler Radar Measurements from Rain: Two Case Studies

In this article, five velocity-based energy dissipation rate (EDR) retrieval techniques are assessed. The EDR retrieval techniques are applied to Doppler measurements from Transportable Atmospheric Radar (TARA)—a precipitation profiling radar—operating in the vertically fixed-pointing mode. A generalized formula for the Kolmogorov constant is...

Advanced Techniques to Process Differential Phase Measurements for Polarimetric X-band Weather Radars

Observations of weather phenomena have attracted many researchers because of their microphysical complexity, space-time variability, and more important, their impact on human life. In the efforts of studying weather, researchers have used a diverse number of instruments to obtain both in-situ (towers, tethered balloons, and weather station...

Adaptive and high-resolution estimation of specific differential phase for polarimetric X-band weather radars

One of the most beneficial polarimetric variables may be the specific differential phase K_DP because of its independence from power attenuation and radar miscalibration. However, conventional K_DP estimation requires a substantial amount of range smoothing as a result of the noisy characteristic of the measured...
