Instrument:UVN (Sentinel-4)
Agencies: ESA [Primary]
 EC
Missions: Sentinel-4 A
 Sentinel-4 B
Status:Proposed
Type:High-resolution nadir-scanning SW spectrometer
Description:Supporting atmospheric composition and air quality monitoring services
Spatial Resolution: < 5 km at SSP, possibly relaxed to 50 km for wavelengths < 308 nm
Swath Width: FOV E-W: 30W-45E @ 40N, N-S: 30N-65N
Wavebands: UV-1: 290 - 308 nm, UV-2: 308 - 400 nm, VIS: 400 - 500 nm, NIR: 750 - 775 nm
Technology: High-resolution nadir-scanning SW spectrometer
Description: Spectrometers to cover bands in UV, Vis, NIR and SWIR with spectral resolution typically of 0.1-0.3 %, required for atmospheric chemistry. Earth viewing so as to measure vertical profiles and total columns. Thousands of channels. Spatial resolution typically 2-20 km. Applicable in LEO and GEO.
