CEOS EO HANDBOOK – INSTRUMENT SUMMARY - UVAS -
Full Name UVAS (Ultraviolet Visible and near-infrared Atmospheric Sounder) Status Being developed
Instrument Agencies CDTI, CSIC Maturity Medium Heritage
Instrument Type Atmospheric chemistry Geometry Nadir-viewing
Instrument Technology High-resolution nadir-scanning SW spectrometer Sampling Sounding
Data Access Constrained Access Data Format
Measurements and Applications High spatial resolution observations of air quality and climate gases such as ozone (O3), nitrogen dioxide (NO2), sulphur dioxide (SO2), formaldehyde (HCHO) glyoxal (CHO-CHO), and aerosols over selected zones of interest (urban and industrialized areas, mayor motorways, and special events like forest fires, volcano eruption and sand storms). Also measurements of halogenated compounds will be performed, including bromine monoxide (BrO) and iodine monoxide (IO).
