After a successful launch in August 1996, the NSCAT instrument on the Japanese Advanced Earth Observing Satellite (ADEOS) began science operations on September 1996. The averaging interval is 1 day for the L3 set of global ocean averaged maps of wind vector solutions.
Teams of scientists
worldwide receive the data to perform research
in areas of international concern.
Additionally, NSCAT data and products
will be available to all users, without restriction, at no more than the
cost of dissemination, regardless of the intended use.

The sample was downloaded from an FTP site of the JPL Physical Oceanography DAAC (PO.DAAC).
This sample L3 granule (1-day averaged global ocean wind map)
shows the state of the near-surface atmosphere at the onset of the
1997-98 El Niño.
Using this data, scientists confirmed that the event began as an unusual weakening of the
trade winds (i.e., wind bars show abnormal west to east winds north and east of New Guinea),
which preceded an increase in sea surface temperatures for the central equatorial Pacific.
NSCAT is the heritage instrument for SeaWinds on the QuikScat satellite (launched June 19, 1999)
and on ADEOS II (launched December 13, 2002).
New ENSO events can be monitored using the SeaWinds instrument .
There is no known quality problem with this granule.
This information came from the EDG for granule: 066.NSCAT_L30_S38.
