ASCAT-B NWP Ocean Calibration and Validation
On September 17, 2012 the Metop-B satellite with onboard the Advanced Scatterometer (ASCAT-B) has been successfully launched. For the ASCAT-B scatterometer, corrections are derived with the use of the NWP ocean calibration (NOC). These corrections are used in the ASCAT wind data processor in order to obtain high-quality winds. The NOC-calibrated ASCAT-B wind product is examined and its quality ...
متن کاملAscat B Ocean Calibration and Wind Product Results
The EUMETSAT Metop-B satellite with onboard the Advanced Scatterometer (ASCAT) has been successfully launched on September 17, 2012. ASCAT-B onboard Metop-B is identical to the already operational scatterometer ASCAT-A onboard Metop-A which was launched in 2006. KNMI has further developed an ocean calibration method for ASCAT-A, based on Numerical Weather Prediction (NWP) wind inputs, the so-ca...
متن کاملAscat Scatterometer Wind Data Processing
The Advanced scatterometer, ASCAT, on MetOp-A was launched on 19 October 2006 as the third wind scatterometer currently in space joining up with the ERS-2 and the SeaWinds scatterometers. Scatterometers measure the radar backscatter from wind-generated cm-size gravity-capillary waves and provide highresolution wind vector fields over the sea with high quality. In this paper we show progress in ...
متن کاملAscat Scatterometer Calibration over the Ocean: Analysis of the 3-dimensional Measurement Space
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 groundbased transponders only in February 2008. However, stable and good quality ASCAT winds are produced ro...
متن کاملValidation and Analysis of Ocean Parameters Using Ascat Data
This project aims to investigate the quality of ASCAT measurements as well as their use for oceanographic purposes. The accuracy of ASCAT retrievals will be mainly based on the use of collocated data from moored buoys, numerical weather prediction models, and satellites. The resulting collocated data will be used to explore the accuracy of the geophysical model function which relates the backsc...
