The simulations include: - S0, an extension of the spin up with constant forcings and land use - S1, including transient CO2, N deposition, and population density - S2, including transient CO2, climate, N deposition, population density, urban, and aerosols - S3, including all transient forcings from the S2 simulation, as well as transient land use change, which includes shifting cultivation, irrigation, and agricultural N fertilizer Simulations are run from 1700 through 2019 using CRU JRA v2 forcing, CO2, land use change, and N deposition data provided by TRENDY. All files include monthly averaged data for the full time period. The "h0" files are grid cell averages, whereas the "h1" files are 1-dimensional files averaged by plant functional type. A script to grid the "h1" files is available on the CTSM python GitHub website. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png HDF5/NetCDF4 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral CLM-LSM > Common Land Model (CLM) Land Surface Model U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > BIOSPHERE > ECOLOGICAL DYNAMICS > ECOSYSTEM FUNCTIONS > BIOGEOCHEMICAL CYCLES EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > TERRESTRIAL ECOSYSTEMS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 1700-01-01 2019-12-31 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 958027.023 https://gdex.ucar.edu/datasets/d583123/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d583123/dataaccess/ https Data Access Related Link download none asNeeded
