Northern Hemisphere vegetation change drives a Holocene thermal maximum

In this data directory are netCDF data needed to evaluate the CESM1.2 results from the referenced publication. There are four categories for separate groupings of data. They are as follows:

CAM

The “CAM” category contains surface temperature (“TREFHT”) and dust aerosol optical depth (“AODDUST1” and “AODDUST2”) data for all 13 simulations presented in this publication. A separate netCDF file exists for each individual simulation, entitled “[SIMULATION_NAME]_CAM_timeseries.nc”, and each file contains monthly output for the 50 years of model data used in the publication.

SST

The “SST” category contains sea surface temperature (“TEMP”) data for five of the simulations presented in this publication. A separate netCDF file exists for each individual simulation, entitled “[SIMULATION_NAME]_SST_timeseries.nc”, and each file contains monthly output for the 50 years of model data used in the publication. The simulations for which SST data are present are:

PICONTROL
6kaPI_VEG
6kaGS
6kaGS+ARC
6ka

FSURDAT

The “FSURDAT” category contains plant functional type percentage (“PCT_PFT”) and monthly leaf area index (“MONTHLY_LAI”) boundary condition data that was used to initialize each simulation presented in this publication. A separate netCDF file exists for each individual simulation, entitled “[SIMULATION_NAME]_FSURDAT.nc”.

RADIATION

The “RADIATION” category contains radiation, cloud, surface temperature, and land fraction data from five of the simulations presented in this publication. This data can be used to recreate the APRP results among other radiative calculations. A separate netCDF file exists for each individual simulation, entitled “[SIMULATION_NAME]_RADIATION_climatology.nc”, and each file contains a monthly climatology (January to December) averaged from the 50 years of model data used in the publication.
