Sentinel-4 mission introduction

The main objective of the Sentinel-4 mission is to monitor key air quality trace gases and aerosols over Europe in support of the Copernicus Atmosphere Monitoring Service (CAMS) at high spatial resolution and with a fast revisit time.

The mission is part of the European Earth Observation Programme "Copernicus" which is run by the European Union together with the European Space Agency (ESA) in ccoperation with the European Environment Agency (EEA).

The Copernicus Space Component comprises a series of space-borne dedicated missions called 'Sentinels' and is developed and procured by the European Space Agency. The missions Sentinel-4, -5 and -5 precursor (S4, S5, S5P, respectively) are conceived as complementary elements of a constellation serving the specific needs of the CAMS. The geostationary S4 mission will provide hourly data on tropospheric constituents over Europe mainly for air quality applications. The target species of the SENTINEL -4 mission include the key air quality parameters NO2 (nitrogen dioxide), O3 (ozon), SO(sulfur dioxide), HCHO (formaldehyde), CHOCHO (glyoxal), and aerosols. Complementarily, the Low Earth Orbiting (LEO) missions S5 and S5p will deliver the S4 target species and additionally CO (carbon monoxide), CH4 (methane), and stratospheric O3 (ozone)with global daily coverage for climate, air quality, and ozone/surface UV applications.

The Space Segment of the Sentinel-4 mission consists of an Ultraviolet-Visible-Near-Infrared (UVN) light imaging spectrometer instrument embarked on the Meteosat Third Generation Sounder (MTG-S) satellite.

Airbus Defense and Space is the prime contractor responsible for the development of Sentinel-4.

ESA Living Planet Symposium 2013

09 - 13 September 2013

The 2013 European Space Agency Living Planet Symposium follows the previous successful symposia held in Bergen (2010), Montreux (2007) and Salzburg (2004). The event will be held in Edinburgh, United Kingdom from 09 to 13 September 2013 and is organised with the support of the UK Space Agency.

The aim of the Symposium is to present the results of ESA EO missions exploitation by providing a forum for investigators to report and discuss results of on-going science activities.
