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 - Lidar/Laser Sounders
ALADIN
ALADIN, on board Aeolus, is a Direct Detection Doppler Wind Lidar operating in the ultraviolet range.
Instrument - Imaging Spectrometers/Radiometers
AATSR
The AATSR instrument aboard Envisat was primarily designed to measure Sea Surface Temperature.
Instrument - Imaging Radars
ASAR
ASAR ensures continuity with the image mode (SAR) and the wave mode of the ERS-1/2 AMI.
Instrument - Spectrometers
GOME
The Global Ozone Monitoring Experiment (GOME) was a nadir-scanning ultraviolet and visible spectrometer for global monitoring of atmospheric Ozone.
Instrument - Spectrometers
GOMOS
GOMOS is a medium resolution spectrometer covering the wavelength range from 250 nm to 950 nm.
Instrument - Imaging Spectrometers/Radiometers
MERIS
The MERIS instrument aboard Envisat was primarily dedicated to providing ocean colour measurements.
Instrument - Imaging Radars
SAR (JERS-1)
The JERS-1 mission had a Synthetic Aperture Radar (SAR) on board.
Instrument - Imaging Spectrometers/Radiometers
Vegetation (VGT)
The main PROBA-V payload is the Vegetation sensor (VGT): a multispectral pushbroom spectrometer.
