The Sentinels are a family of missions developed by ESA for the operational needs of the Copernicus programme. Each mission, carrying a different range of technologies, will focus on various aspects of Earth Observation: Atmospheric, Oceanic, and Land monitoring, and the data will be of use for a broad range of applications.
Sentinel-5 Precursor – also known as Sentinel-5P – is the first Copernicus mission dedicated to monitoring our atmosphere. It consists of one satellite carrying a spectrometer, with the main objective of performing atmospheric measurements relating to air quality, climate forcing, ozone and UV radiation.
