Project Duration: 2013 - 2016
Solicitation:NASA: Carbon Monitoring System (2013)
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, meth ... [more]
