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 - Radar Altimeters
The RA-2 instrument aboard Envisat acquired radar altimetry data over ocean, land and ice surfaces.
Instrument - Imaging Spectrometers/Radiometers
The MWR instrument, on board Envisat mission, measured integrated atmospheric water vapour column and cloud liquid water.
Instrument - Imaging Radars
ASAR ensures continuity with the image mode (SAR) and the wave mode of the ERS-1/2 AMI.
