ERS-1

European Remote Sensing Satellite 1

NASA’s provision of the European Space Agency’s (ESA) European Remote Sensing satellites (ERS-1 and ERS–2) Synthetic Aperture Radar (SAR) data archive via the ASF DAAC is free and open by agreement between NASA and ESA. As part of the Earth observation Heritage Data Program (LTDP+), the ERS-1 and -2 missions provide scientists with historically accurate and easily accessible information to help further understand the dynamics of our planet.

ASF holds a subset of all ERS data.

Overview

ERS- 1 primarily collected high resolution imagery within the ASF and the McMurdo, Antarctica, station masks. The datapool contains ASF standard beam odd frames, as well as the first and last frame of each imaged swath. ERS 1 flew in tandem with ERS-2 for 9 months in 1995/1996. Both sets of data are suitable for interferometry.
