ASCAT scatterometer ocean calibration

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
A new scatterometer, the so-called Advanced scatterometer (ASCAT), onboard MetOp-A satellite was successfully launched on October 19 2006. During the commissioning phase one of the main goals is to accurately calibrate the instrument. The radar backscatter has been calibrated using three ground-based transponders in February 2008.

Assessment of Spatiotemporal Variations in Wind Field Measurements by the Chinese FengYun-3E Wind Radar Scatterometer

IEEE Access, 2023
The purpose of this study is to analyze the spatiotemporal variations in wind field measurements obtained from the Chinese FengYun-3E (FY-3E) Wind Radar (WindRAD) scatterometer. To assess the performance of the wind field retrievals, we compare the FY-3E

Improvements of storm surge forecasting in the Gulf of Venice exploiting the potential of satellite data: the ESA DUE eSurge-Venice project

European Journal of Remote Sensing, 2017
The northern Adriatic Sea is affected by storm surges, which often cause the flooding in Venice and the surrounding areas. We present the results of the eSurge-Venice project, funded by the European Space Agency (ESA) in the framework of its Data User ...

Aquarius Scatterometer Calibration

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
In this paper, we discuss the Aquarius scatterometer calibration, starting with the instrument calibration. We examine the stability of Aquarius as quantified using the loop-back power and estimated receiver gain to shown Aquarius has been extremely stable to order 0.1 dB since mission start.
