Abstract:
This data publication includes the newest version update (3.0) of the National Forest Carbon Monitoring System (NFCMS). It provides 30-meter resolution data of forest extent, forest type, forest carbon stocks, historical forest conversion (1990-2020), and potential future forest carbon stocks for the years 2050 and 2070 based on a 30-years and 50-years, respectively, grow-only scenarios where no disturbances (harvest, fire, insects) nor changes in climate are considered. This version of NFCMS included significant updates in Forest Inventory and Analysis (FIA)-fitted carbon curves as well as forest extent and forest disturbance history. All units have been switched to metric tons of CO₂e per acre [also equal to megagrams of CO₂e per acre]. Forest carbon stocks are provided at the regional level (Northeast, Northern Lake States, Northern Prairie States, Pacific Northwest, Pacific Southwest, Rocky Mountain North, Rocky Mountain South, South Central, and Southeast). The data are also provided at the conterminous-United States (CONUS) level, which are simple mosaics of the regional maps and do not involve continental-level averages or other model adjustments.
