Accuracy | Instrument Description | Measurement Technology | Timeline |
| ASTER | Operational | Surface and cloud imaging with high spatial resolution, stereoscopic observation of local topography, cloud heights, volcanic plumes, and generation of local surface digital elevation maps. Surface temperature and emissivity. ASTER SWIR detectors are no longer functioning due to anomalously high SWIR detector temperatures. ASTER SWIR data acquired since April 2008 are not useable, and show saturation of values and severe striping. All attempts to bring the SWIR bands back to life have failed, and no further action is envisioned. | n/a |  |
| ATLAS | Operational | Provide date on ice sheet height and sea ice thickness, land altitude, aerosol height distributions, cloud height and boundary layer height. | Lidar altimeter | |
| AVHRR/3 | Operational | Measurements 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 | |
| HSI-2 (HJ-2A) | Operational | Hyperspectral measurements for environment and disaster management operations. | n/a | |
| MSU-MR | Operational | Parameters of clouds, snow, ice and land cover, vegetation, surface temperature, fire detection. | n/a | |
| SAR (RADARSAT-2) | Operational | All-weather images of ocean, ice and land surfaces. Used for monitoring of coastal zones, polar ice, sea ice, sea state, geological features, vegetation and land surface processes. | Imaging radar (SAR) | |
| SAR (RCM) | Operational | All-weather, C-band data to support ecosystem monitoring, maritime surveillance and disaster management. | Imaging radar (SAR) | |
| SAR-L | Operational | Land, ocean, emergencies, soil moisture, interferometry, others. | Imaging radar (SAR) | |
| SGR-ReSI-CDHS | Operational | Ocean winds, waves, soil moisture, flooding, ice, snow. Similar to SGR-ReSI-Z, but with a smaller Zynq, and only supports 2 RF channels, only allowing collection of single frequency and single polarisation. | n/a | |
| SIRAL | Operational | Marine ice and terrestrial ice sheet thickness measurement. | Radar altimeter | |
| SRAL | Operational | Marine and land services. | Radar altimeter | |
| Imaging Microwave Radiometer | Being developed | A conical scanning total power radiometer operating in 5 bands (L/C/X/K/Ka) to provide high-spatial resolution microwave imaging radiometry measurements and derived products with continuous global coverage and sub-daily revisit in the polar regions and adjacent seas. | n/a | |
| IRIS | Being developed | Ku-band Interferometric Synthetic Aperture Radar Altimeter (with added Ka-band channel for snow depth retrieval and in combination with AMR-CR MW Radiometer for ice&snow classification and wet troposphere correction) to cover the needs for continuous monitoring of sea ice
thickness and land ice elevation measurement after Cryosat-2, with enhanced performance. | Radar altimeter | |
| SGR-ReSI-Z | Being developed | Ocean winds, waves, soil moisture, flooding, ice, snow | n/a | |
| Advanced MSU-MR | Proposed | Parameters of clouds, snow, ice and land cover, vegetation, surface temperature, fire detection. | n/a | |
