WitrynaUsing analytical rain cell models and constant wind fields, the effects of partial beam filling by rain is investigated. The model results show that Ku-band scatterometer … Witryna22 sty 2014 · The Advanced Scatterometer (ASCAT) onboard the Metop satellite series is designed to measure the global ocean surface wind vector. Generally, ASCAT provides wind products at excellent quality. Occasionally, though, ASCAT-derived winds are degraded by rain. Therefore, identification of rain can help to better understand the …
Impact of rain on spaceborne Ku-band wind scatterometer data
Witryna1 mar 2012 · The combination of the SeaWinds scatterometer and AMSR radiometer on the Midori-II satellite made it possible to develop rain correction algorithms for scatterometer data, which can either minimize or remove the effect of rain on the scatterometer winds. Described below are several alternative approaches that have … WitrynaResults of an investigation are given describing two-di-two-dimensional rain cell size statistics employing radar and disdrometer data bases spanning more than 5 years and all seasons. Radar data were obtained employing the SPANDAR radar located at the NASA Wallops Flight Facility, Wallops Island, Virginia. These data corresponded to … pit boss electric smoker cover
Rain Effects on CFOSAT Scatterometer: Towards an Improved …
WitrynaIt is shown that the backscatter measurements at low incidence angles are much less affected by rain than those at higher incidence angles, and an adapted wind inversion scheme is proposed to further improve the CSCAT wind quality under rainy conditions. Rain is known to be the most significant phenomenon in degrading the Ku-band … WitrynaRain affects scatterometer radar measurements in three ways: 1) rain attenuates the transmitted signal and the signal backscattered from the sea surface (i.e., two-way attenuation); 2) rain ... Witryna1 sie 2006 · Abstract The value of Quick Scatterometer (QuikSCAT) measurements of 10-m ocean vector winds for marine weather prediction is investigated from two Northern Hemisphere case studies. The first of these focuses on an intense cyclone with hurricane-force winds that occurred over the extratropical western North Pacific on 10 … pit boss electric smoker app
