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 - Imaging Spectrometers/Radiometers
ATSR
The Along Track Scanning Radiometer (ATSR) on board ERS-1 and ERS-2 mission consisted of two instruments, an Infra-Red Radiometer and a Microwave Sounder.
Instrument - Imaging Spectrometers/Radiometers
MWR (ERS)
The microwave radiometer (MWR) instrument on board the ERS-1 and ERS-2 missions provided measurements of the integrated atmospheric water vapour column and cloud liquid water content.
Instrument - Radar Altimeters
RA (ERS)
The Radar Altimeter (RA) was a Ku-band (13.8 GHz) nadir-pointing active microwave sensor, on board ERS-1 and ERS-2 missions, designed to measure echoes from ocean and ice surfaces.
Instrument - Spectrometers
SCIAMACHY
SCIAMACHY was an instrument on board the Envisat satellite that measured atmospheric chemistry.
Instrument - Imaging Spectrometers/Radiometers
MERIS
The MERIS instrument aboard Envisat was primarily dedicated to providing ocean colour measurements.
Instrument - Imaging Spectrometers/Radiometers
CHRIS
Compact High Resolution Imaging Spectrometer (CHRIS) provided data of spectral reflectances.
Instrument - Imaging Spectrometers/Radiometers
AATSR
The AATSR instrument aboard Envisat was primarily designed to measure Sea Surface Temperature.
Instrument - Interferometric Radiometers
MIRAS
The MIRAS instrument is a passive microwave 2-D interferometric radiometer onboard the SMOS satellite.
