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.

scatterometers

WS (ERS-2)

The ERS-2 Wind Scatterometer obtained information on wind speed and direction at the sea surface.

a-spectrometers-radiometers

MWR (ERS-2)

Used for measurement of the integrated atmospheric water vapour column & cloud liquid water content

a-altimeters

RA (ERS-2)

The RA on ERS-2 was a Ku-band nadir-pointing active microwave sensor designed to measure echoes from ocean and ice surfaces.

a-spectrometers-radiometers

ATSR-2

Used for measuring sea-surface temperatures, cloud-top temperatures and vegetation monitoring.

Campaigns

Learn about the ground-based, ship-borne, balloon-borne, and airborne campaigns and small satellite field experiments that validate orbiting ESA EO satellites and support future mission development.

BACCHUS-DOC

BACCHUS-DOC

The BACCHUS-DOC Radar and Optical Campaign was an area mapping project of vineyards near Frascati (Italy). ESA required high resolution geo-referenced airborne SAR data of different wavelength and polarisation (preferably polarimetric).
