Data sets for Ocean winds over the Tropical Pacific
For all these data sets the wind field is a vector with u
(South to North) and v (West to East) components. Units are
meters/second. The main interest in these data sets is combining the two
sets of wind field spatial measurements to produce a better estimate. The
data from the National Center for Environmental Prediction is the result
of a complicated assimilation process using available observational data
and a large physical model of the atmosphere.
All data are centered around November 7th, 1996 (day 312/366).
During this time a large tropical cyclone (Dale) was present in
the data region.
- Gridded climate analysis (NCEP) wind data
at four time intervals on November 7, 1996.
Data set is a 1008 X 10 table with the first two columns
the grid position in longitude and latitude. The remaining 8
columns are the 4 pairs of u and v components.

- NSCAT surface wind measurements
from 9PM Nov 6th
through 3AM Nov 8th, 3 hours on either side of the NCEP output and
restricted to the same region in the
Pacific. The data have been aggregated into 6 hour blocks to
correspond to the NCEP time periods. Note that because of the
orbit of the satellite, measurements locations are irregular and
so each record has a separate location (see the plot link
mentioned above). Each data set is a table with 5
columns, with values: longitude, latitude, u, v, and the exact
time of measurement.
