PHOENIX – Greenhouse gas monitoring was a hot topic at the American Meteorological Society’s annual conference with international agencies discussing a global constellation and companies showing a new generation of sensors.
“We are looking quite hard in Europe, in the Committee on Earth Observation Satellites and the Coordination Group for Meteorological Satellites at a carbon monitoring verification system,” said Ken Holmlund, chief scientist for Europe’s meteorological agency Eumetsat. “Europe is planning three to four greenhouse gas monitoring satellites. We are looking at an international partnership and hoping the United States and Asia will respond to the call.”
Through the Paris climate agreement, 174 countries and the European Union committed in 2015 to undertake efforts to mitigate global warming and to report progress in reducing greenhouse gas emissions every five years beginning in 2023. (President Trump announced plans in 2017 to withdraw the United States from the pact.)
A global greenhouse-gas-monitoring constellation would support national activities to track and report emissions, Holmlund said, calling it “a tool for everybody to work more efficiently.”
China, Europe, Japan and the United States already fly greenhouse gas monitoring satellites but many carry experimental sensors. A global constellation would require satellites and sensors in both ...
