ERS-1

ESA's ERS-1 Satellite

08/31/2000 -- IMPORTANT information for users of ERS-1 and ERS-2 altimetry data from this site regarding:

• The USO and SPTR corrections.
• A 40.9 cm bias that exists bewteen the ERS-1 and ERS-2 altimeter ranges.

Overview

The European Space Agency's (ESA) ERS-1 radar altimeter satellite was launched in July of 1991 and provided data from August 1991 to July 1996 in an orbit that extended coverage over the ice sheets to +/- 81.5 degrees. ERS-2 was launched in April of 1995 and will give similar coverage. The waveform analysis product produced by the UK-PAF, required to process ice sheet elevations has had numerous problems and large delays in release. As of February 1998, we have what we believe to be the complete data set for the ERS-1 data which includes a 168 day repeat cycle, 1 year of 35-day repeats, and several months of 3-day repeats.
