QuikSCAT Product Description
This page provides a brief description of QuikSCAT wind vector
product. For additional information about SeaWinds or QuikSCAT, please
visit JPL's Scatterometer web site.
Figure below portrays current QuikSCAT retrieval process,
which consists of several steps:
Processing satellite measurements (sigma0s)
using JPL retrieval algorithm and deriving up to 4 solutions (wind vectors)
at JPL, NASA
Generating 6 hours forecast for global
winds (First Guess) at NCEP, NOAA
Comparing multiple JPL solutions for
wind vectors with the NCEP first guess wind vectors and selecting
one selected wind vector at NESDIS, NOAA
As a result of this retrieval process, wind vectors
are produced each of which represents a wind vector cell of the size 25
x 25 km with 72 cells along the scan line (swath width is 1800 km).
