Model Predictions of Future Ecosystem Dynamics in California’s Sierra Nevada

The datasets provide simulations of future ecosystem dynamics in California’s Sierra Nevada produced with the Ecosystem Demography model version 2.2 (ED2.2; https://github.com/EDmodel/ED2). Simulations were initialized with the Global Ecosystem Dynamics Investigation (GEDI) L2B Canopy Cover and Vertical Profile Metrics Data, Global Footprint Level V002 (https://search.earthdata.nasa.gov/). Annual model outputs are available for 2020–2099 at four Critical Zone Observatory (CZO) flux-tower sites: San Joaquin Experimental Range (SJER), Soaproot Saddle, Providence Creek (P301), and Shorthair Creek. HDF5 file prefixes denote sites as follows: soilGRID0100 = SJER, soilGRID0982 = Soaproot, soilGRID0716 = P301, and soilGRID0649 = Shorthair. The datasets include annual time series of ecosystem states, such as diameter at breast height (DBH, cm), above-ground biomass per cohort (AGB_CO, kg C/plant), above-ground biomass growth (AGB_GROWTH, kg C/m²/yr), and mortality (AGB_MORT, kg C/m²/yr). Soil carbon pools are also provided, including the fast pool (FAST_SOIL_C) representing metabolic litter and microbes, the structural pool (STRUCTURAL_SOIL_C) representing structural debris, and the slow pool (SLOW_SOIL_C) representing humified and passive carbon (all in kgC/m²).
