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-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.

scatterometers

SAR (ERS-2)

The SAR instrument aboard ERS-2 was capable of high precision change detection of surface heights.
