QSCAT and ADEOS-II / NCEP Blended Ocean Winds (version 1.0)

Ocean surface wind data are derived from spatial blending of
high-resolution satellite data from tandem SeaWinds missions
(QSCAT and ADEOS-II)  and  global
weather center  analyses (NCEP), resulting in  high temporal
and spatial resolution  datasets (6-hourly, and 0.5 by 0.5 degree).


This two-scatterometer blending product is only available for the duration
of the ADEOS-II mission (April 10 to October 24 2003).  The blending scheme is a
variation of the single-scatterometer blending (QSCAT only, ds744.4): the main
difference is a 7.5 hour time-window used for blending versus the sliding 12-hour
window in the QSCAT only blending.


Available  data  products are:  the  blended product, which consists of QSCAT and ADEOS-II blended with NCEP analyses;
and the low-wavenumber analysis field, which is the
NCEP analyses splined to the 0.5 by 0.5 degree grid.
These fields are available as wind components or as windstress curl.  Details of the method
are summarized in

this document.


Data file formats and read routines are the same as for QSCAT/NCEP blending (ds744.4).
