GHGSat Unveils
Satellite Imagery

In May 2017, GHGSat unveiled sample imagery from its demonstration satellite, Claire. GHGSat has detected emissions of methane, an important greenhouse gas, from a hydroelectric facility under construction in Africa. GHGSat is making sample imagery and data for this facility available for evaluation by qualified parties.

Claire captures an array of over 200,000 atmospheric measurements around an industrial facility in a few seconds. These measurements are processed to produce imagery showing a “heat map” of greenhouse gas concentrations from the facility.

Patented Technology:
How it Works


GHGSat satellites measure any site in the world, within days. GHGSat aircraft sensors are dispatched to high-value areas, on demand.

Data Processing

GHGSat’s technology measures the absorption of light with very high resolution in spectral bands for gases of interest

Products & services

GHGSat delivers raw measurements of gas concentrations and value-added analyses of these measurements using proprietary algorithms
