Abstract:
A comprehensive carbon monitoring system will likely include the integration of bottom-up and top-down estimates. Current bottom-up estimates for global agricultural lands often consist of individual inventory-based estimates per country. This results in a global bottom-up estimate that is not consistent in underlying soils or land cover data, methods of estimating carbon stocks and fluxes, or estimates of uncertainty. The proposed research will use off-the-shelf data, models, and remote sensing products to develop a global bottom-up, inventory-based estimate of carbon stocks and fluxes for agricultural lands, including vegetation and soils. The annual estimates will be generated using globally consistent datasets, C estimation methods, and methods for estimating uncertainty. Land area will be defined by a fusion of MODIS land cover data and inventory-based land area data. Methods will coincide with current national and international methods and protocols for compatibility with ongoing efforts in carbon monitoring, reporting, and verification. While these estimates can be used independently for synthesis and assessment reports, they can also be (a) used in conjunction with similar global data on forest carbon stocks and fluxes, thereby generating one comprehensive bottom-up, inventory-based estimates, and (b) used to evaluate the latest state-of-the-art monitoring components generated by NASA in the coming years. A scoping study will also be conducted to determine how the bottom-up, inventory-based estimate can be improved upon or integrated with other satellite-based bottom-up estimates, and how the global agricultural estimate can be integrated with previously conducted estimates on global forest carbon.
