SASS data were acquired at 4.45 km resolution. While originally designed for wind observation, scatterometer sigma0 measurements have proven useful in a variety of land and ice studies. To aid in the application of these measurements, Brigham Young University (BYU) prepared this dataset consisting of enhanced resolution images generated from SASS sigma0 measurements.
This data set consists of enhanced resolution images generated from Seasat sigma0 measurements.
This data set contains images from 16 regions around the globe. Images are made from the Seasat Scatterometer Geophysical Record data files and processed using the BYU SIRF algorithm. To produce the highest possible spatial resolution as well as to ensure full coverage over the images, multiple orbit passes are combined. The study period was from July through October, 1978.
The parameters provided in the images include polarization, geographical region, time span, image type, and reconstruction technique. This 1978 data set provides a baseline for studies of global change. These data are available via FTP.https://nsidc.org/data/NSIDC-0258/versions/1GET DATAhttp://podaac.jpl.nasa.gov/PRODUCTS/p175.htmlGet External DataPROJECT HOME PAGEhttp://podaac.jpl.nasa.gov/PRODUCTS/p175.htmlData set descriptionCEOS IDN DIFVERSION 9.92005-01-262023-05-23NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCFull Dataset Citation2005. <i>BYU High Resolution Images of Seasat Sigma0 Measurements.</i> [indicate subset used].
