MWI
Microwave Imager | Being developed
| Measure cloud liquid water content, solid/liquid precipitation information, total column water vapour and temperature profiles, sea ice parameters, sea surface temperature, sea surface wind speed. | n/a |  |
Multiview Thermal-Infared
Multiview Thermal-Infared | Approved
| Observations of motion occurring at or near Earth’s surface. | n/a | |
Passive Synthetic Aperture Radar
Passive Synthetic Aperture Radar | Approved
| High-resolution observations of motion occurring at or near Earth’s surface. Record radio waves originating from the accompanying Copernicus Sentinel-1 satellite as they bounce back from the Earth’s surface, allowing scientists to measure small shifts in the shape of the land surface, such as those related to earthquakes and volcanic activity, as well as of land ice and sea ice. | n/a | |
