| hasSummary |
-
The SeaWinds instrument on the QuikSCAT satellite is a specialized
radar that measures near-surface wind speed and direction at a 25 km
resolution. This instrument has been measuring winds over
approximately 90% of the ice-free ocean since 19 July 1999. These
data were prepared by Remote Sensing Systems (RSS). A new
geophysical model function, called Ku-2001, was used in this version
of the dataset and is considered an improvement over the earlier
Ku-2000 and the old NSCAT-2 functions because of more accurate
retrievals of high winds (greater than 30 m/s). The dataset time
series ends in June 2002, however, continuing data are available
from RSS.
Many more details concerning the Ku-2001 data are available from
the RSS website [http://www.remss.com/]. These data are also
directly available from RSS.
Notice 07/28/2006: JPL PO.DAAC has initiated reprocessing of all
ADEOS-II and QuikSCAT data with superior algorithms for retrievals
in high wind speed and light rain areas. This reprocessing could
effect this dataset. More information is available at JPL PO.DAAC
[http://podaac.jpl.nasa.gov/].
