Impact of rain cell on scatterometer data
Witryna[1] Rain can strongly modify the normalized radar cross section (NRCS) measured by Ku-band scatterometers and alter the wind vector retrieval. Part 1 of this paper … 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 ...

Witryna16 kwi 2010 · The scatterometer SeaWinds on QuikSCAT provided regular measurements at Ku-band from 1999 to 2009. Although it was designed for ocean applications, it has been frequently used for the assessment of seasonal snowmelt patterns aside from other terrestrial applications such as ice cap monitoring, … WitrynaObservations of sea surface wind field are critical for typhoon prediction. The scatterometer observation is one of the most important sources of sea surface winds, which provides both wind speed and wind direction information. However, the spatial resolution of scatterometer wind is low. Synthetic Aperture Radar (SAR) can provide …
Witryna12 kwi 2024 · Additionally, analysis of the moist static energy budget shows that surface fluxes help support the westward-propagation of diurnal precipitation. These results—based on novel satellite data and reanalysis—are consistent with previous studies that have examined the impact of the land-sea breeze on the diurnal cycle of … WitrynaThe accuracy of Ku-band ocean wind scatterometers (i.e., NSCAT and SeaWinds) is impacted to varying degrees by rain. In order to determine how to best flag rain-contaminated wind vector cells and ultimately to calibrate out the effects of rain as much as possible, we must understand the impact of rain on the backscatter …
