blue arrow DESCRIPTION

This is a RA-2 Sensor and Geophysical Data Record (SGDR) Full Mission Reprocessing (FMR) v3 product. This FMR follows the first Envisat Altimetry reprocessing Version (V2.1) completed in 2012.

The GDR and S-GDR data products were reprocessed for all cycles from 6 to 113 (May 2002 to April 2012) into a homogeneous standard in NetCDF format (close to Sentinel-3).

The Sensor Data Record (SGDR) Product from RA-2/MWR includes the data in the GDR product (https://earth.esa.int/web/guest/-/ra-2-geophysical-data-record-1470) (RA-2 geophysical data, MWR data) and also RA-2 averaged waveforms (18Hz) and RA-2 individual waveforms (1800Hz). This product is a continuation of ERS RA data.

This data product has a coverage of 1 pass, pole-pole, a spatial sampling of about 390 m along track and a size of 31 to 40 Mbytes, depending on presence of individual waveforms.

The radiometric accuracy is 0.2 dB and auxiliary data include: Orbit state vectors (DORIS, FOS), RA2 and MWR characterisation data, Platform attitude, Gain calibration, USO frequency, ECMWF data, time relation, leap second, Ionospheric corrections, geoid, mean sea surface, slope data, and tide model (ocean, earth, loading, pole).

Please consult the Envisat RA-2/MWR Product Quality Readme file before using the data.
