Resumen

In the context of a previous study, the Spatial Response Function (SRF) size and orientation of the QuikSCAT full resolution (FR) backscatter measurements have been characterized in order to assess the Land Contribution Ratio (LCR). The LCR information can be used for correcting or filtering out the backscatter measurements near the coast with the final aim of improving the sampling and the quality of coastal winds derived from QuikSCAT and other pencil-beam scatterometers. The study concludes that improved coastal winds are only possible when the backscatter noise is thoroughly characterized, an information which is unfortunately unavailable in the QuikSCAT FR files. As such, this follow-up study aims at characterizing the noise in the QuikSCAT backscatter measurements and implementing a noise-dependent backscatter integration scheme for coastal wind retrieval purposes

Actividades del proyecto

Actividades dentro del proyecto:
a) To characterize the noise in the QuikSCAT backscatter measurements (slices) according to their distance to the egg (footprint) centroid
b) To validate a backscatter measurements correction/filtering scheme which accounts for slice-dependent noise in specific coastal test areas which are not affected by either orography or human activities
c) To assess a weighted regression scheme in order to take into account backscatter measurement noise
d) To set-up an operational processor for coastal wind field retrieval.
