Instrument DescriptionMeasurement TechnologyTimeline
MLS (EOS-Aura)
Microwave Limb Sounder (EOS-Aura)
Operational
Measures lower stratospheric temperature and concentration of H2O, O3, ClO, HCl, OH, HNO3, N2O and SO2.Limb-scanning MW spectrometer
OSIRIS
Optical Spectrograph and Infra-Red Imaging System
Operational
Detects aerosol layers and abundance of species such as O3, NO2, OClO, BrO and NO. Consists of spectrograph and IR imager.n/a
UVNS (Sentinel-5 precursor)
TROPOMI
Operational
Supporting atmospheric composition and air quality monitoring services.n/a
UVAS
UVAS (Ultraviolet Visible and near-infrared Atmospheric Sounder)
Being developed
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).n/a
UVNS (Sentinel-5)
Ultra-violet Visible Near-infrared Shortwave-infrared spectrometer
Being developed
Supporting atmospheric composition and air quality monitoring services. Measurements of atmospheric trace gases, primarily O3, NO2, SO2, HCHO, CH4 and CO.n/a
PCW PHEOS - Atmospheric
Polar Highly Elliptical Orbit Science Weather, Climate & Air Quality Mission
Proposed
Complement PCW operational numerical weather prediction. Will also collect information about atmospheric gaseous and aerosol composition to better understand transport and climate processes. .n/a
UVN (Sentinel-4)
UV-visible- near infrared imaging spectrometer (Sentinel-4)
Proposed
Supporting atmospheric composition and air quality monitoring services.n/a
