| EMI-2 | Operational | Ozone profile and total-column or gross profile of other species. Tracked species: BrO, ClO H2O, HCHO, NO, NO2, O3, SO2 and aerosol | n/a |  |
| NACHOS Hyperspectral Imager | Operational | | n/a | |
| OMS-N | Operational | SUVI uses extreme ultraviolet spectral lines to achieve long-term and continuous observations of the sun, so as to obtain high temporal and high spatial resolution images of the solar corona. | n/a | |
| TANSO-3 | Operational | Global and regional concentration mapping of CO2, CH4, and NO2 for global monitoring of GHG concentrations, verification of emission inventories, and detection of emissions from large sources. | n/a | |
| UVN (Sentinel-4) | Being developed | Supporting atmospheric composition and air quality monitoring services. | n/a | |
| UVNS (Sentinel-5) | Being developed | Supporting 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. | n/a | |
| CO2I | Approved | Pushbroom 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. | n/a | |
