Sentinel-3A to provide Earth observation data worldwide & Free of cost

Posted on

Sentinel-3 will provide high-accuracy optical, radar and altimetry data for marine and land services, measuring variables such as sea surface topography, sea- and land-surface temperature, ocean colour and land colour with high-end accuracy and reliability. The first
Sentinel-3 satellite (S-3A) was launched on 16 February 2016 and is supporting ocean forecasting systems, as well as environmental, agriculture and climate monitoring. A second satellite (S-3B) is scheduled for launch in 2017.

Third Sentinel in orbit

The mission is expected to begin operations in five months, delivering Earth obseration data worldwide and free of charge for all users.

The Sentinel-3A satellite will deliver data within three hours of sensing, 24 hours a day, 365 days a year. While these data will be fed primarily into the Copernicus Marine Environment Monitoring Service, all the Copernicus services will benefit from it, as the satellite will systematically measure also Earth’s land, ice and atmosphere with a suite of cutting-edge instruments.
