Radar reflectivity calibration using differential propagation phase measurement

Differential Reflectivity (ZDR) Calibration for CASA Radar Network using Properties of the Observed Medium

The use of X-band radars for weather surveillance and research, either as standalone or in collaborative and adaptive networks, has advanced significantly during the past years. With advantages that include lower cost, smaller infrastructure and easier deployment, and the capability to provide the required resolution and coverage when sampling the atmosphere at the mid to long range low altitud...

Differential Reflectivity Calibration for NEXRAD

P2.2 Segmenting Radar Reflectivity Data using Texture

A novel method of performing multiscale segmentation of radar reflectivity data using statistical properties within the radar data itself is introduced. The method utilizes a K-Means clustering of texture vectors computed within the

Differential power calibration for weather radar

Dual polarized weather radars, radars that can transmit both horizontal (H) and vertical (V) polarized waves, are becoming more common in the world. Dual polarization is accomplished via fast alternate transmission of H and V polarization or simultaneous H and V polarization transmission. The simultaneous H and V transmit mode is becoming quite popular since a high power, costly, polarization s...

Quantification of Cloud Microphysical Parameterization Uncertainty Using Radar Reflectivity

Uncertainty in cloud microphysical parameterization—a leading order contribution to numerical weather prediction error—is estimated using a Markov chain Monte Carlo (MCMC) algorithm. An inversion is performed on 10 microphysical parameters using radar reflectivity observations with vertically covarying error as the likelihood constraint. An idealized 1D atmospheric column model with prescribed ...
