sentinel-1

Sentinel-1

Always useful, even when the skies are overcast

Sentinel-1 is a two satellite, polar-orbiting RADAR constellation The radar collects data from Earth in all weather conditions, even through clouds. This data is suitable for monitoring the stability of infrastructures, among others. Sentinel-1 achieves a resolution of 5 by 20 m, comparable to the surface area of a commercial warehouse.

Sentinel-2

Sentinel-2

Unprecedented view of Earth

The Sentinel-2 mission consists of 2 polar-orbiting satellites that return over the same location every 5 days. There they image the Earth under constant sun elevation. They generate multispectral images covering a 290-km wide strip (e.g., from Calais to Verviers) and with a resolution up to 10 m – allowing viewers to distinguish single-family homes.
The satellites provide an unprecedented view of Earth and changes in vegetation, land and water masses, waterways and coastal areas.

Sentinel-3

Land and sea data from space

Sentinel-3 delivers highly accurate and reliable optical, thermal and altitude data for marine and land use. The Sentinel-3A and -3B satellites measure the topography of the sea surface, the temperature at sea and on land, and the colour of land and ocean.
Sentinel-3 images achieve a resolution up to 300 m.

S5-P

Sentinel-5P

Monitoring various atmospheric components and air quality

Sentinel-5 Precursor is designed to daily observe and monitor various atmospheric components and air quality. With an unprecedented resolution of 3.5 × 5.5 km2, the satellite and its on-board Tropospheric Ozone Monitoring Instrument (TROPOMI) can detect air pollution and its sources at sub-urban scale.

PROBA-V

PROBA-V

Global vegetation on the map

PROBA-V is a miniature satellite measuring less than a cubic metre. Every two days, PROBA-V maps the entire land cover and vegetation growth across the entire globe. Data from the satellite helps to assess climate change and monitor agriculture and food safety, among others.

Copernicus Land Monitoring service

Satellite and sensor collaboration

 

Copernicus Land Monitoring Service combines data from PROBA-V and data from sensor networks on the earth’s surface. This results in up-to-date geographical information, intended for water and forest management, agriculture and food safety, nature conservation and spatial planning, to name a few.

 

LAI (Leaf Area Index)

  • shows how dense the vegetation cover is, so it is biomass indicator
  • synthesis over 10 days
  • resolution of 300 metres

fAPAR (Fraction of Absorbed Photosynthetically Active Radiation)

  • shows the photosynthesis activity for green vegetation
  • synthesis over 10 days
  • resolution of 300 metres
