Product description

PRODUCT TYPE data INPUT DATA FDGDR OUTPUT TYPE along-track
SATELLITE Envisat AGENCIES ESA GRID TYPE
CONTENTS This product is generated within a few days (3 to 5), using restituted auxiliary data (meteorological fields, pole location, DORIS ionospheric data) and a DORIS preliminary orbit. The product is re-tracked (waveform data are fully processed in the ground processor to extract the geophysical parameters) and mainly contains datation, geo-location, output from re-trackers (range, wind speed, significant wave height, etc.), at 1 Hz plus some 18 Hz parameters (range, orbital altitude). In order to retrieve the geophysical parameters over all types of surface (ocean, ice, sea-ice, etc.), four specialised re-trackers are continuously run in parallel (over all surfaces): Ocean re-tracker, Ice-1 re-tracker, Ice-2 re-tracker and Sea-Ice re-tracker.
