Please contact us if there are any discrepancies or inaccuracies found below.
|Description||Contains Seasat-A Scatterometer (SASS) Sigma-0 measurements for the entire Seasat mission, from July 1978 until October 1978, produced by Frank Wentz at Remote Sensing Systems. The data are presented chronologically by swath and consist of the forward and aft values, binned in 50 km cells. For each cell there are 17 parameters including time, location, incidence angle, sigma-0, instrument corrections, and data quality.|

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.
