| Session Description | This session focuses on understanding both natural and anthropogenic carbon fluxes using atmospheric observations from various observational platforms, including in-situ, e.g. tower and flask-based measurements, as well as remotely sensed, e.g. satellites. Multiple satellite platforms now provide routine measurements of greenhouse gases, such as GOSAT (CO2+CH4), OCO-2 (CO2), TanSat (CO2), and the recently launched Sentinel-5 Precursor (CH4). These provide opportunities to make great gains in our knowledge of the carbon cycle, if the challenges associated with both the GHG measurements as well as the inverse flux modeling can be overcome. We particularly invite contributions on: 1) Science-based results driven by the top-down measurements, regarding either natural or anthropogenic fluxes, 2) advances in the remote sensing of the carbon-based GHGs CO, CH4 and CO2, as well as Solar-Induced Chlorophyll Fluorescence (SIF) either through new measurements or improved retrieval algorithms; and 3) advances in the inverse modeling of GHG budgets, e.g. via strategies for coupling atmospheric inversions to biogeochemical models, or through the novel use of multiple species (e.g. H2O and CO2, carbon isotopes, OCS and CO2, and SIF). |
