The netcdf files in this directory comprise climate model output from the Community Earth System Model for experiments looking at leaf trait acclimation to elevated carbon dioxide. For further description of the model and configuration for these experiments please see the accompanying manuscript:

Full time series for the entire simulation period is provided for the following variables, indicated in the filename:
TREFHT (temperature at 2m, K)
FSNS (net solar flux at surface, W/m2)
FSNSC (clearsky net solar flux at surface, W/m2)
T (temperature, K)
CLOUD (cloud fraction)
RELHUM (relative humidity, %)
Q (specific humidity, Kg/Kg)
GPP (gross primary productivity, gC/m2/s)
NPP (net primary productivity, gC/m2/s)
TLAI (total projected leaf area index, m2/m2)
QVEGT (canopy transpiration, mm/s)
QVEGE (canopy evporation, mm/s)
QSOIL (ground evaporation, mm/s)

Also archived are the annual average values for all variables from both the land and atmosphere models in files with Òyear_avgÓ in the name.
