Partial Beam Blockage Correction Using Polarimetric Radar Measurements

On the Correction of Partial Beam Blockage in Polarimetric Radar Data

Three methodologies for correcting the radar reflectivity factor (ZH) in the presence of partial beam blockage are implemented, compared, and evaluated using a polarimetric radar dataset from the North American Monsoon Experiment (NAME) in northwestern Mexico. One methodology uses simulated interactions between radar beams and digital terrain maps, while the other two invoke the self-consistenc...

Combined Doppler and Polarimetric Radar Measurements: Correction for Spectrum Aliasing and Nonsimultaneous Polarimetric Measurements

Combining Doppler and polarimetric information is advantageous for atmospheric studies. On the one hand, Doppler information gives insight into the microphysical and dynamic properties of radar targets, that is, radial velocity and its variability. The polarization diversity, on the other hand, has a strong link to the microphysical properties of targets such as shape and orientation. Polarimet...

7.2 Radar Precipitation Estimates in Mountainous Regions: Corrections for Partial Beam Blockage and General Radar Coverage Limitations

The prevailing raindrop shape obtained by polarimetric radar measurements

Polarimetric radar measurements are used to retrieve properties of raindrop distributions. While there has been extensive research conducted on microphysical retrievals such as hydrometeor classification or hail detection, there has not been much research into polarimetric radar based deduction of raindrop shape even though the shape of raindrops plays a critical role in rainfall estimation fro...

Rainfall retrieval from polarimetric X-band radar measurements

Dual polarization radars have shown considerable improvement of quantitative estimation of rainfall rate and raindrop size distribution (DSD) parameters. Most studies have been done with S and C-band radars and only a few studies with higher X-band weather radars. X-band radars have the advantages of lower cost and higher differential phase shift but with higher attenuation too. Furthermore, th...
