This product provides choes from ocean surface from the ERS radar altimeter along the satellite track. Wind speed modulus, wave height and sea surface elevation can then be retrieved (using precision orbits derived from the onboard laser retro-reflector). The datasets in the product include - over dated and geolocated 7 km wide cells (sensor footprint) - all sensor parameters, range and altitude elements used for geophysical quantities retrievement, all backscatter coefficient, wind speed, significant wave height elements computed, but also the ATSR/RW radiometer data (brightness temperature at 23.8 GHz and 36.5 GHz, water vapour content, liquid water content) used to correct altimeter measurements. Land cells are flagged.
This product is available in 2 different versions. The level 1, called OPR1, is an intermediate product processed with the preliminary orbit, The level 2, called OPR2 is the final product processed with the precise orbit. |
