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
