IASI
Infrared Atmospheric Sounding Interferometer | Operational
| Measures tropospheric moisture and temperature, column integrated contents of ozone, carbon monoxide, methane, nitrous oxide and other minor gases which affect tropospheric chemistry. Also measures sea surface and land temperature. | n/a |  |
IRAS
InfraRed Atmospheric Sounder | Operational
| Atmospheric sounding for weather forecasting. | n/a | |
ROSA
Radio Occultation Sounder for the Atmosphere | Operational
| Climate change studies. High-vertical resolution temperature-humidity sounding for NWP. Space weather. | n/a | |
ROSA
Radio Occultation Sensor for Atmosphere | Operational
| Enables measurement of water vapour and temperature profiles in the tropics. | n/a | |
CWFMS
Canadian Wildland Fire Monitoring Sensor | Being developed
| Measurements are: Fire Radiative Power (FRP), hotspot locations, rate of spread, burned area mapping. Data products generated: 1) Fire maps, showing location, extent, and timing of forest fire events; 2) Fire characteristics, such as fire line intensity, rate of spread and fuel consumption; 3) Plume dynamics through smoke transport maps and plume heights; 4) Mass of carbon released into atmosphere. | n/a | |
IASI-NG
Infrared Atmospheric Sounding Interferometer - New Generation | Being developed
| Measures profiles of atmospheric temperature, humidity, ozone, carbon monoxide, columns of methane, nitrous oxide, and other minor gases, and sea, ice, and land surface temperature and emissivity. | n/a | |
MATHS
Millimeter wave Atmosphere Temperature and Humidity Sounder | Proposed
| Integrated water vapour, cloud liquid water and precipitation for temperature sounding | n/a | |
