Ultraviolet, Visible and Near-Infrared
Supporting chemistry applications
The Ultraviolet, Visible and Near-Infrared (UVN) instrument is a Copernicus Sentinel 4 instrument designed for geostationary chemistry applications.

The UVN is a spectrometer measuring in the ultraviolet (UV: 305–400 nm), the visible (VIS: 400–500 nm) and the near infrared (NIR: 750–775 nm), with a spatial sampling distance of around 8 km.
Its observations are restricted to European area coverage, from 30 to 65º N in latitude and 30º W to 45º E in longitude, depending on seasonality (Figure 1). The observation repeat cycle period will be approximately one hour.
