INSTRUMENTS
Explore the many instruments the European Space Agency use to observe the Earth. ESA offer data from a wide range of optical, radar, atmospheric, altimetric and gravimetric instrumentation.
Instrument - Scatterometers
SAR (ERS) Processor Releases
Processor Releases It should be noted that for SAR, each product ordered is processed directly from the raw data, using the current version of the SAR
Instrument - Radar Altimeters
RA (ERS)
operational modes (ocean or ice) the RA provided information on significant wave height; surface wind speed; sea surface elevation, which relates to ocean currents
