The Copernicus Sentinel missions support atmospheric monitoring by providing timely, continuous and independent data on the atmosphere, and provide data to support federal, national and local studies and activities, and help in addressing a variety of policy areas.
OLCI supports investigations into atmospheric composition (mainly aerosols and water vapour) which is a fundamental parameter for climate studies, and also contributes to the measurements of the downwelling solar radiation (long-wave and short-wave) at the Earth's surface and Top Of Atmosphere, which are critical to the estimation of the global Surface Radiation Budget (SRB).
The MWR instrument measures the atmospheric water content in liquid and vapour phases. This information will be used to enable the Sentinel-3 mission to meet the required altimetry accuracy requirements for the measurements acquired by the SRAL instrument on the same platform.
The multi-angle, multi-wavelength viewing geometry of the SLSTR instrument supports the characterisation and investigation of cloud properties through the development of operational cloud products.
The TROPOMI instrument aboard Sentinel-5P is a dedicated atmospheric monitoring mission, and measures air quality, ozone and ultraviolet radiation, and provides climate monitoring and forecasting.
