Impact of rain cell on scatterometer data
Witryna1 wrz 2024 · Rain affects the wind measurement accuracy of the Ku-band spaceborne scatterometer. In order to improve the quality of the retrieved wind field, it is … Witryna3 kwi 2024 · Satellite scatterometer wind retrieval is affected by rain. Both the precipitating clouds in the atmosphere and the sea surface rain effects can enhance or reduce the backscatter signal. Ku-band scatterometer retrievals suffer more rain effects than C-band scatterometer due to the shorter wavelength. Because of the lack of …

WitrynaRain 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 … Witrynascatterometer data are strongly affected by rain, that they are extremely sensitive to the rain distribution within scatterometer resolution cells, and that the normalized …
Witryna18 mar 2024 · Second, the proposed model is not suitable for the data affected by rainfall. The inner beam and the outer beam correspond to different changes of NRCS caused by rainfall. For the scatterometer working at a medium incidence angle, NRCS will gradually increase when the rainfall rate gradually increases [26,27,28,29]. Witryna22 gru 2011 · The presence of widespread rain in these storms impedes the estimation of surface winds from the radar cross section measurements, when using a Ku-band …
Witryna19 lut 2016 · The data employed in the study were the “Active Product”, which is a consistent dataset produced based on the outputs of ERS-1/2 scatterometer and its directly applicable successor Advanced Scatterometer (ASCAT) in terms of the method . The ERS scatterometer has been flown on board the ERS-1 (1991–1996) and ERS … Witryna15 lip 2003 · The model results show that Ku-band scatterometer data are greatly affected by rain and are extremely sensitive to the distribution of rain within …
Witrynarain within scatterometer cells can significantly modify the sea surface backscatter coefficient and hence alter the wind vector retrieval. These perturbations can hamper …
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 … income tax averaging lump-sum distributionWitryna12 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 … income tax averaging for retireesWitrynaRain 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 ... income tax averaging irsWitryna[7] TOURNADRE J, QUILFEN Y.Impact of rain cell on scatterometer data:2.Correction of Seawinds measured backscatter and wind and rain flagging[J].Journal of Geophysical Research, 2005, 110(C7):C07023.
