Objectives and Applications

Sensing of greenhouse gases (CO2 & CH4) at high resolution. "GHGSat'’s unique sensing technology which is able to detect methane emissions from sources 100 times smaller than any other satellite, but with a resolution 100 times higher. That means GHGSat can detect and quantify methane emissions from point sources as small as oil & gas wells. No other commercial operator or state-funded space organization can do this.".

The GHGSat constellation aims to become the global reference for the remote sensing of greenhouse gas (GHG) emissions from any source in the world. The GHGSat constellation currently consists of GHGSat-D (Claire), GHGSat-C1 (Iris) and GHGSat-C2 (Hugo). Additional launches are foreseen over the coming years in order to achieve a 10 satellite constellation. The on-board spectrometer allows measurement of the vertical column abundances of greenhouse gases, especially methane. ESA offers access to worldwide GHGSat data (both archived and new acquisitions) via the TPM scheme. Read more
