In a first-of-its-kind partnership, GHGSat and the Shanghai Institute of Technical Physics (SITP), Chinese Academy of Sciences collaborated to tackle one of the biggest challenges in methane monitoring. By combining GHGSat’s targeted high-resolution satellite measurements with the wide-area coverage of China’s Advanced Hyperspectral Imagers (AHSI), they created a new approach to tracking methane emissions globally.
Over the past year, this partnership analyzed more than 500 satellite scenes, covering over 130,000 square kilometers. Together, they identified over 2,400 methane emission events by blending GHGSat’s ability to zoom in on specific sources with AHSI’s wide-area coverage. This collaboration achieved something no single system could do on its own—pairing targeted, frequent observations with broad geographic coverage to capture a more complete picture of methane emissions.
By leveraging cutting-edge technologies—GHGSat’s precise Fabry-Pérot interferometer and AHSI’s advanced spectrophotometry—the team successfully measured methane emissions ranging from small leaks to massive emissions exceeding 5,000 kg/hr. This partnership also tackled one of methane monitoring’s biggest challenges: cross-validation. By analyzing overlapping detections from both systems, the team was able to validate data, showing how this integrated approach enhances accuracy.
Methane monitoring is at a crossroads. The world needs scalable solutions that work now, and this partnership is proof that integration is the way forward.
