Abstract:
The NASA Carbon Monitoring System effort seeks to apply satellite remote sensing resources along with observational and modeling capabilities to improve monitoring of carbon stocks and fluxes, particularly as they contribute to the development of Monitoring, Reporting and Verification (MRV) system capabilities. Our prior NASA-funded research employs a combination of models and remotely-sensed and in situ observations to develop georeferenced products and associated uncertainties for land-ocean exchange of carbon, air-sea exchanges of carbon dioxide, and coastal to open ocean exchanges of carbon. A major aspect of this project has been to establish and populate geospatial portals for sharing and analysis of carbon datasets and products. The primary region of study has been the Mississippi River watershed and northern Gulf of Mexico. The unique nature of our approach, coupling models of terrestrial and ocean ecosystem dynamics and associated carbon processes, allows for assessment of how societal and human-related land use, land use change and forestry (LULUCF) and climate-related change affect terrestrial carbon storage and fluxes, as well as export of materials through watersheds to the coastal margins. Here, we propose to extend the domain of our observational and integrated terrestrial-ocean ecosystem model system to include the southeastern U.S. and South Atlantic Bight. In addition to land-ocean and sea-atmosphere exchanges, we will utilize satellite observations together with the capabilities of the terrestrial ecosystem model to characterize and quantify terrestrial carbon storage and fluxes, including land-atmosphere fluxes of both carbon dioxide and methane. Our approach will include assembling model products along with associated uncertainties and errors in a geospatial framework that will facilitate decision support for carbon and land use management. Objectives of the proposed research include the following: 1) Expand the spatial domain of our observational and integrated modeling approach to include the Mississippi River basin and southeastern U.S., and examine terrestrial carbon storage and fluxes including characterization and quantification of biomass and carbon stocks in and land-atmosphere, land-ocean, and sea-atmosphere fluxes of carbon dioxide and methane; 2) Examine different LULUCF scenarios within the terrestrial domain and different climate scenarios to assess effectiveness of carbon management strategies; 3) Engage with other CMS projects and stakeholders (e.g., USDA, National Climate Assessment, etc.) to identify user needs related to carbon management and MRV activities, modify and expand the scope of information based on user feedback, and explore possible transition of prototype products to fully operational status. The Application Readiness Level of our prior CMS project was rated as ARL-4 (Initial Implementation and Verification in Laboratory Environment), with the potential to advance to ARL-6 (Demonstration in a Relevant Environment). A goal of this proposed research will be to advance this capability to ARL-7 (Application of Prototype in Partnerís Operational Decision Making Environment). Our proposed effort will aid in the effective implementation of MRV approaches, which require an understanding of the contributions of individual forest and other ecotypes beyond local to regional and national scale carbon processes. Furthermore, our proposed effort will aid in governance and decision support related to carbon management, including the ability to evaluate different LULUCF scenarios in the context of changing climate conditions. Extended impacts of forest and other land use management strategies on carbon storage and transport, including in soils and into watersheds and coastal margins will be assessed. Finally, this information will be readily accessible as a geo-referenced product to support operational needs of stakeholders.
