Building on the success of the Copernicus Sentinel-5 Precursor satellite, the new Copernicus Sentinel-5 mission introduces an advanced imaging spectrometer. This cutting-edge instrument is integrated into the MetOp Second Generation A-type weather satellites, working in synergy with other onboard instruments.

Sentinel-5 delivers daily global data on key air pollutants, essential climate variables, and stratospheric ozone that protects us from ultraviolet radiation. The mission’s high-resolution imaging spectrometer operates across seven spectral bands, spanning the ultraviolet, visible, near-infrared and shortwave infrared ranges to measure a host of trace gases, including ozone, nitrogen dioxide, sulphur dioxide, formaldehyde, glyoxal, carbon monoxide, and methane, as well as aerosols and UV index. Additionally, the instrument will probe the vertical distribution on some of these components.
