As a core activity of the North American Carbon Program (NACP), the North American Forest Dynamics (NAFD) project is designed to produce a detailed assessment of forest dynamics over the U.S in a quarter century from 1986 and 2010 to better understand how forest disturbance and recovery modulate biosphere-atmosphere carbon fluxes. The NAFD study is enabled by the NASA Earth Exchange (NEX) collaborative computing facility, which provides massive computing and storage capacity, as well as convenient access to all required Landsat and ancillary datasets. This disturbance product provides detailed depictions of individual forest disturbance patches across the conterminous US for each year from 1986 to 2010. Over the 25 years analysis period (1986-2010), extensive regions of the US forests are disturbed one or more times. Nationally, the mean disturbance rate for the coterminous United States is calculated as 1.4+/-0.4% per year. The product has been validated using reference data derived using the TimeSync tool at sample locations selected from across the nation. Further analysis is being conducted to identify causal agent and to evaluate the impact of forest disturbance history on regional carbon budget.
