| AMI | Operational | Continuous 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. | Multi-purpose imaging Vis/IR radiometer | |
| CERES | Operational | Long 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 | |
| Imager (INSAT 3D) | Operational | Cloud cover, severe storm warnings/monitoring day and night (type, amount, storm features), atmospheric radiance winds, atmospheric stability rainfall. | Multi-purpose imaging Vis/IR radiometer | |
| NISTAR | Operational | Measure the energy emitted and reflected by the Earth. | n/a | |
| VIIRS | Operational | Global observations of land, ocean, and atmosphere parameters: cloud/weather imagery, sea-surface temperature, ocean colour, land surface vegetation indices. | Multi-purpose imaging Vis/IR radiometer | |
| FEI | Being developed | Provide images in a narrow spectral band centered at 10.5µm. | n/a | |
| HIS | Being developed | Pushbroom-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 | |
| Land Surface Temperature Radiometer | Being developed | VNIR/SWIR/TIR radiometer with three independent focal planes fed by a single telescope to acquire images of all land and coastal areas with high radiometric accuracy and spatial resolution. Acquistion are during day and night in TIR bands and during day in VNIR/SWIR bands.
Monitoring evapotranspiration (ET) rate at European field scale by capturing the variability of Land Surface Temperature (LST) (and hence ET) enabling more robust estimates of field-scale water productivity. Supporting a range of additional services benefitting from TIR observations (e.g. soil composition, coastal zone management, High-Temperature Events (HTE), urban heat islands). | Multi-purpose imaging Vis/IR radiometer | |
| Libera | Being developed | 5-year design mission. The mission focuses on understanding the flow of energy out of the planet and how it changes over time. | n/a | |
