Summary:
Coastal winds are of paramount importance for a large variety of both civil and scientific applications. Today, scatterometer-derived winds represent the golden standard for satellite-derived winds.
However, the impact of land contamination in coastal areas may lead to undesired biases that can be mitigated by careful pre-processing. In particular, excessively contaminated footprints should be discarded, and the low contaminated ones should be “corrected” to remove the land contribution. EUMETSAT OSI-SAF plays a leading role in the distribution of operational winds and research and development (R&D). One of its aims is to improve wind accuracy and sampling, especially near the coast. This project is the follow-up of the projects VS20_01 and VS20_03. The final aim of these projects is to improve both the accuracy and sampling of the winds derived from the American scatterometer SeaWinds onboard the satellite mission QuikSCAT.
The main goals of this project are:
- Implement a Land Contribution Ratio (LCR) based Normalized Radar Cross Section (NRCS) correction scheme
Assess the most accurate averaging procedure among the boxcar averaging and the noise-based averaging of the available measurements
Implement the sea NRCS regression scheme in the PenWP processor
