BYU High Resolution Images of ERS Sigma0 Measurements, Version 1

The C-band scatterometers on ERS-1 and ERS-2 provided normalized radar cross section (sigma0) measurements of the Earth's surface. 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 data set consisting of enhanced resolution images generated from ERS sigma0 measurements.

This data set contains images from 16 regions around the globe. Images are made from fast-delivery products sent to JPL and are processed using the BYU SIR algorithm. Multiple passes of the spacecraft are combined to produce a higher spatial resolution (at a cost of reduced temporal resolution). The study period was from 1 January 1992 to 17 May 1996 and 3 June 1996 to 20 January 2001.

The parameters provided in the images include geographical region, time span, image type, and reconstruction technique. These data are available via FTP.
