ABIOperationalDetects clouds, cloud properties, water vapour, land and sea surface temperatures, dust, aerosols, volcanic ash, fires, total ozone, snow and ice cover, vegetation index.n/a
AMIOperationalContinuous monitoring capability for the near real-time generation of high-resolution meteorological products and long-term change analysis of land/sea surface temperature and cloud coverage.n/a
AVHRR/3OperationalMeasurements of land and sea surface temperature, cloud cover, snow and ice cover, soil moisture and vegetation indices. Data also used for volcanic eruption monitoring.n/a
CERESOperationalLong term measurement of the Earth's radiation budget and atmospheric radiation from the top of the atmosphere to the surface; provision of an accurate and self-consistent cloud and radiation database.n/a
MISROperationalMeasurements of global surface albedo, aerosol and vegetation properties. Also provides multi-angle bidirectional data (1% angle-to-angle accuracy) for cloud cover and reflectances at the surface and aerosol opacities. Global and local modes.n/a
SSIMOperationalSolar irradiance monitoring.n/a
TROPOMIOperationalSupporting atmospheric composition and air quality monitoring services.High-resolution nadir-scanning SW spectrometer
CLIMBeing developed3-band cloud pushbroom imager for detecting low and high clouds in the spatial sample of CO2I allowing to remove these data from the retrieval process.n/a
CO2IBeing developedPushbroom scanning spectrometer to provide relatively high spatial resolution CO2, CH4 and NO2 observations in support of estimating anthropogenic emissions of CO2 and CH4 in Copernicus. In addition, high quality NO2 and solar-induced fluorescence will be operationally delivered.High-resolution nadir-scanning SW spectrometer
GXIBeing developedDetects clouds, cloud properties, water vapour, land and sea surface temperatures, dust, aerosols, volcanic ash, fires, total ozone, snow and ice cover, vegetation index.n/a
HISBeing developedPushbroom-type dual-prism Imaging Spectrometer with high radiometric accuracy and medium Signal-to-noise Ratio, operating from UV (320 nm) to SWIR (2400 nm) , based on a single MCT Detector/focal plane. The HIS aims at accurate spectral imaging on land and ocean for climatological background radiometric data acquistion and supporting cross-calibration with other stellites/sensors and on PICS/instrumented sites with highest resolution (50 m)n/a
UVNS (Sentinel-5)Being developedSupporting atmospheric composition and air quality monitoring services. Measurements of atmospheric trace gases, primarily O3, NO2, SO2, HCHO, CH4, CO, CHOCHO as well as Aerosols and UV Index.High-resolution nadir-scanning SW spectrometer
