Tabular data of carbon dynamics for conterminous U.S. forests from 2001-2020 Tabular data output from a series of modeling simulations for forest ecoystems of the continental United States (CONUS). We linked the LUCAS model of land-use and land-cover change with the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) to project changes in forest ecosystem carbon balance resulting from land use, land use change, climate change, and disturbance from wildfire and insect mortality. The model was run at a 1-km spatial resolution on an annual timestep for the years 2001 to 2020. We simulated four unique scenarios, consisting of a climate change only scenario, a land-use change only scenario, a combined climate and land-use change scenario, and a no change scenario. Results presented here... Categories: Data; Tags: CONUS, CONUS, CONUS, Carbon balance, Climate change, All tags...

Data include a raster map of CONUS with pixel values representing the number of years in which it was classified as forest across the annual LCMAP time series (0-36), as well as tabular data summarizing forest change by area and proportion for each of the 48 conterminous U.S. states and the District of Columbia. Tabular output includes information on 1) the area classified as forest in each State by year, 2) the forest area in each frequency...

For the 1970-2001 period, we used the USGS's LUCAS model to "backcast" LULC, beginning with the 2001 initial conditions and ending with 1970. For future projections, the model was initialized in 2001 and run forward on an annual time step to 2100. In total 5 simulations were run with 10 Monte Carlo replications of each simulation. The simulations include: 1) Historical backcast from 2001-1970, 2) Business-as-usual (BAU) projection from 2001-2101, and 3) three modified BAU projections based on California Department of Finance population projections based on high, medium, and...
