CryoSat
earth explorers

CryoSat

CryoSat determines variations in the thickness of continental ice sheets and marine ice cover. Europe's first ice mission is an advanced radar altimeter specifically designed to monitor the most dynamic sections of Earth's cryosphere.

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.

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.

CryoVEx 2016 (Spring)

CryoVEx 2016 (Spring)

CryoVEx 2016 campaign was primarily carried out to follow up on a recommendation given within ESA CryoVal Land Ice project (2014-2015), where it was found that the traditional under-flights of the Cryosat-2 satellite were inadequate.

CryoVEx ASIRAS

CryoVEx ASIRAS

The CryoVEx 2014 airborne campaign was conducted as two separate operational periods. The sea ice activities covering large parts of the western Arctic Ocean were planned to take place early in the season to make sure the weather was stable.
