The method is based on a direct comparison of measured backscatter data with simulated backscatter data from Numerical Weather Prediction (NWP) winds. This NWP Ocean Calibration tool (NOC) is used to improve the scatterometer wind products and can be used to eliminate systematic interbeam biases and across-swath dependencies (when present) in the wind product. Monte Carlo simulations are useful to assess the accuracy of the NOC method and to determine the sensitivity with respect to binning and sampling errors. As such, simulation runs with realistic “true” wind distribution and realistic measurement and NWP wind-component error values are performed. A reprocessing of QuikSCAT data over its whole lifespan (1999-2009) is being performed by KNMI. The averaged NOC residuals over a longer period are used to calculate correction factors and used to improve the wind retrieval This work is done in the framework of the EUMETSAT OSI SAF and its associated visiting scientist scheme. The Quikscat winds produced at KNMI can be freely obtained from the OSI SAF web site. QDP has been funded by EUMETSAT in the context of the NWP SAF and can be obtained free of charge from the NWP SAF web site Peer reviewed 2015-06-26T07:16:40Z 2015-06-26T07:16:40Z 2014-09 comunicación de congreso http://purl.org/coar/resource_type/c_5794 EUMETSAT Meteorological Satellite Conference (2014) http://hdl.handle.net/10261/117209 en Sí none
