CEOS Member Agencies with interests in CO2- and CH4-measuring LEO missions will sponsor or co-sponsor one or more workshops (and require a written report) to refine the scientific and policy requirements for quantitative data on atmospheric CO2 and CH4 from low Earth orbit. These meetings should involve the key international science and applications communities in specifying the technical foundation and scientific requirements for as well as the societal benefits of future missions to quantify atmospheric CO2 and CH4 from low earth orbit.
Reported under action VC-05
Since about ten years the International Workshop on Measurement of GHGs from Space (IWGGMS) is organized regularly every year). The workshop comprises the postulated action items. There is a growing interest over the years by scientists and agency representatives from the Americas, Asia, and Europe (ESA, NASA, JAXA, CSA, NOAA, CNES, DLR) [IWGGMS-10 at ESA/ESTEC 2014: ~ 200 attendees] representing the science and application community as well. The workshop is organized yearly in turn between the US, Europe and Asia.
Also, leverages existing efforts at various space agencies: e.g., NASA OCO-2 science team, ESAGHG CCI, and other national programs (e.g., CAS, CMA)
