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 | |
TGSP

| Trace gas measurements. | n/a | |
TES
Tropospheric Emission Spectrometer | No longer operational
| 3D profiles on a global scale of all infra-red active species from surface to lower stratosphere. Measures greenhouse gas concentrations, tropospheric ozone, acid rain precursors, gas exchange leading to stratospheric ozone depletion. | High-resolution nadir-scanning IR spectrometer | |
