# Commission Implementing Decision (EU) 2018/620 of 20 April 2018 on the technical specifications for the Copernicus service component pursuant to Regulation (EU) No 377/2014 of the European Parliament and of the Council (Text with EEA relevance), Division 5.1: Satellites-Based Observations

Extent: E+W+S+N.I.

C3S shall use operational and past satellite-based instruments to provide products for climatology, reanalysis and validation purposes.
The C3S shall use the following types of data:
(a) radiometer and spectrometer data acquired in the domain covering the infrared to the microwave wavelengths to measure brightness temperature and then derive several geophysical parameters (wind vector, ozone, surface temperature);
(b) GPS-radio occultation data to derive information on the atmosphere's temperature, pressure and water vapour content;
(c) scatterometer data to measure near-surface wind speed and direction;
(d) altimeter data to derive ocean wave height.
The service shall be also supported by data and products from the Sentinel satellites.
