Copernicus Sentinel-1
Sentinel-1 provides all-weather, day and night radar imagery for land and ocean services. The twin satellites Sentinel-1A and Sentinel-1B were respectively launched on 3 April 2014 and on 25 April 2016.
Copernicus Sentinel-2
Sentinel-2 provides high-resolution optical imagery for land services. It provides for example, imagery of vegetation, soil and water cover, inland waterways and coastal areas. Sentinel-2 also delivers information for emergency services. The twin satellites Sentinel-2A and Sentinel-2B were respectively launched on 23 June 2015 and on 7 March 2017.
Copernicus Sentinel-3
Sentinel-3 provides high-accuracy optical, radar and altimetry data for marine and land services. It measures variables such as sea-surface topography, sea- and land-surface temperature, ocean colour and land colour with high-end accuracy and reliability. The twin satellites Sentinel-3A and Sentinel-3B were respectively launched on 16 February 2016 and on 25 April 2018. EUMETSAT operates the satellites and delivers the marine mission, while ESA delivers the land mission.
Copernicus Sentinel-4
Sentinel-4 will provide data for atmospheric composition monitoring. Its objective is to monitor key air quality trace gases and aerosols over Europe at hight spatial reslution with a fast (hourly) revisit time. It will be a payload embarked on EUMETSAT's Meteosat Third Generation (MTG), which will be launched in the coming years.
Copernicus Sentinel-5
Sentinel-5 will also be dedicated to atmospheric composition monitoring. It will be a payload embarked on a EUMETSAT's Metop Second Generation (Metop-SG) to be launched in the coming years. It will provide accurate measurements of key atmospheric constituents such as ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide, methane, formaldehyde, and aerosol properties.
Copernicus Sentinel-5P
Sentinel-5 Precursor is a satellite mission launched on 13 October 2017. It is a gap filler mission aiming to provide data continuity until the launch of Sentinel-5, the dedicated atmospheric Copernicus mission, to be launched in the coming years.
Copernicus Sentinel-6
Sentinel-6 provides high accuracy altimetry for measuring global sea-surface height, primarily for operational oceanography and for climate studies. It is a cooperative mission developed in partnership between Europe (EU, ESA and EUMETSAT) and the U.S. (NOAA and NASA). It was launched in 2020.
