-
Ocean surface wind data are derived from spatial blending of
high-resolution satellite data (SeaWinds instrument on the QuikSCAT
satellite - QSCAT) and global weather center re-analyses (NCEP),
resulting in high temporal and spatial resolution datasets
(6-hourly, and 0.5 by 0.5 degree) of u- and v- wind vector
components and windstress curl. The global coverage datasets begin
in July 1999 and ends in July 2009.
Surface wind component and wind stress curl fields are available in
three forms: 1) a product that is the blended wind field output, 2)
fields consisting of the NCEP re-analyses spline interpolated to the
0.5 by 0.5 degree grid (i.e. no QSCAT data blended), and 3) a
product that is output from an intermediate step in the blending
process that consists of the superposition of QSCAT observations on
NCEP before blending. This product is useful to identify the
satellite data swaths in each composite of 12-hours of QSCAT
observations.
CAUTION: This blended wind product was developed for general
circulation scale analyses - see these cautionary notes
[https://rda.ucar.edu/datasets/ds744.4/docs/Blended_Winds_Caution].
The blending methodology is summarized in this document
[https://rda.ucar.edu/datasets/ds744.4/docs/Blended_Winds_Summary].
NOTE: The QSCAT satellite has permanent failed so this data time
series has ended.
