Short NameUCLA_DEALIASED_SASS_L3
DescriptionContains dealiased ocean wind vector components (zonal and meridional) derived from the Seasat-A Scatterometer (SASS) provided on a global 1x1 degree grid. Dealiasing of the SASS data was achieved manually using ship observations in a joint effort between JPL, UCLA and AES. This data set underwent restoration in 1997. Data are provided in ASCII text files at six hour intervals.

Name: Seasat-A Scatterometer System (SASS)
Swath Width: 1900 km
Description: The Seasat-A Satellite Scatterometer (SASS) contains four dual-polarized (both vertical and horizontal) fan-beam radar antennas, which were designed to produce an X-shaped scanning pattern across Earth's surface. The SASS radar was designed to transmit at a frequency of 14.6 GHz (Ku-band). SASS provided 95% global coverage every 36 hours at a sampling footprint of approximately 50 km within a 1900 km-wide swath. SASS was designed to measure radar backscatter sensitive to wind speeds from 4-26 m s-1 referenced to 10 meters above the ocean surface. SASS was intended to be accurate to within 2 m s-1 or 10% (whichever is greater) of the observed wind speed and within 20¿ of the observed wind direction.
