The proposal will address this challenge through:

• Deploying large coordinated in situ, ground-based and airborne observation monitoring campaigns over different Earth’s ecosystems (terrestrial, terrestrial-aquatic continuum, and marine sub-seafloor) and key anthropogenic sources (e.g. agriculture, waste, mining, oil and gas industry) with comparable and scalable measurement approaches.
• Running these campaigns during an extended period of time and planning them beyond the duration of the projects, building on existing measurement infrastructures and initiatives, in order to support the validation of satellite products, but as well to support the development of new and enhancement of existing models and data assimilation techniques.
• Evaluating temporal change in methane release over centuries at selected, relevant sites from existing long-time series.
• Advancing towards an integrated methane observing system (on “facility scale”) that capitalises on the latest advances in observations from satellite, in situ, ground-based remote sensing and airborne instruments as well as results from citizen observations.
• Advancing the capacity of models and data assimilation techniques, related to methane emissions through specifically exploiting novel medium and high-resolution satellite data (e.g. GHGSat, PRISMA, Sentinel-2, Landsat-8/9, Worldview-3).
• Delivering inverse modelling to separate methane sources and sinks and to attribute inverse modelling estimated fluxes to specific processes building on sufficient spatial resolution to identify the origin, for instance, of large local emissions.
• Advancing towards an enhanced spatially and temporary high-resolution global and regional assessment of the methane sources and sinks and its dynamics over time, the related natural and anthropogenic processes, and impacts on climate.
