CEOS Instrument: UVAS (Ultraviolet Visible and near-infrared Atmospheric Sounder)




Instrument:UVAS
Agency: CDTI
Mission: Ingenio
Status:Approved
Type:High-resolution nadir-scanning SW spectrometer
Description:The main scientific objectives of the UVAS mission are: - Observe with unprecedented high spatial resolution observations of air quality gases ozone (O3, nitrogen dioxide (NO2), sulphur dioxide (SO2), formaldehyde (HCHO) and glyoxal (CHO-CHO), and aerosols over selected urban areas. - Produce highly-spatially resolved observations of the major greenhouse gases: carbon dioxide (CO2), methane (CH4) and water vapor (H2O) over selected observation areas. - Combine high spatial resolution observations with atmospheric models to better quantify sources and sinks of specific gases. - Assimilate the remote sensing measurements into global chemistry-climate models to examine the processes linking atmospheric composition and climate.
Spatial Resolution: 20Km nominal, 5Km zoom
Swath Width: N/A
Wavebands: NIR 1500-1750 nm O2 A-band 650 to 770 nm UV/VIS 290 to 490 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.
