The CEOS Carbon Subgroup (recommended in Carbon-Action-38)? will work to encourage the production and availability of high-quality, consistent long time series data products based on multiple sensors and missions for carbon and climate science and for model-data and data-data intercomparison exercises. ?
Multiple agency involvement including NASA (OCO-2), JAXA (GOSAT, GOSAT-2), and ESA (SCIAMACHY, Sentinel-5P), DLR (MERLIN), CMA/CAS (TanSat) in atmospheric composition; IGCO/GEO? call for observations from all domains (atmosphere, land, ocean) and all VCs will need to contribute to long-term time series products.
