The United States Weather Surveillance Radar-1988 Doppler (WSR-88D) radar network has been upgraded to dual-polarization capabilities, providing operational and research meteorologists with a wealth of new information regarding the types and distributions of hydrometeors within precipitating storms, as well as a means for improved radar data quality. In addition to the conventional moments of r...

Preamble This is the final report to Lockheed Martin on the requirements for a phased array weather radar. Discussed herein are those meteorological requirements that need to be met by weather radars having either reflector type antennas or active phased array elements. These requirements impact the design of the antenna, the transmitter-receiver, and signal processor. Justifications for these ...

Recently, some spaceborne polarimetric synthetic aperture radars, such as TerraSAR X (Xband), RADARSAR-2 (C-band) and PALSAR (L-band), are available to measure a scattering matrix of terrain and polarimetric data analysis techniques are being developed for terrain classification, forest biomass and soil moisture estimations, etc. Thus polarimetric calibration is necessary to obtain the accurate...

This paper presents some data from an two months experiment. The examined dataset included three polarimetric X-band weather radars supplemented by MRRs, disdrometers and rain-gauges. The focus of the paper is on the radar observations. The recorded rain events were of low intensity and this didn’t permit a more advanced evaluation of radars performance. Thus, instead of just showing some daily...

With the new data collected with polarimetric radars comes a set of new data quality issues and artifacts. It is important for these artifacts to be recognized and understood as such, thereby allowing operational meteorologists to focus on the interpretation of the physically important observations. In this third part of the series, artifacts found in polarimetric radar data are described and e...

The Mini-RF radar aboard India’s lunar Chandrayaan-1 satellite [1] (2008-9) was the first polarimetric synthetic aperture radar (SAR) outside of Earth orbit. The architecture of that radar—and of its more advanced two-frequency sibling on NASA’s Lunar Reconnaissance Orbiter [2] (2009)—is hybrid dual-polarimetric [3][4]. This architecture is a form of compact polarimetry [5] in which the dual-re...

The COPE field campaign operated from the 3rd July to the 20 th August 2013, with ground operations based in Davidstow Cornwall where the X-band polarimetric Doppler radar was located. Figure 1 shows the location of Davidstow, the Chilbolton S-band polarimetric Doppler radar and the C-band radars within the Met Office network. The Met Office Cobbacombe C-band radar was operational although not ...

Radar meteorology applications rely on pulsed weather radars that survey the atmosphere and estimate a set of meteorological variables for each resolution volume. The reliability of these applications depends on the quality of the supplied data. To reduce the statistical uncertainty of estimates of spectral moments and polarimetric variables for each resolution volume, weather radars often aver...
