CAM3 climatologies



We provide climatology of CAM3 in various configurations (present-day climate conditions, climate scenarios for increased carbon dioxide, and specified sea surface temperature simulations) and resolutions. These climatologies can be used to gauge cloud climate feedbacks for a wide range of climate regimes.

Details
  • Simulations have been conducted in different configurations (AMIP runs, SOM runs, SOM 2xCO2 runs) for the Eulerian dynamical core at T42 and T85 resolutions.

  • The simulations have names indicating that they were performed using different development versions of the model. All of the configurations used produce the same climate.

  • We provide model versus observations plots for the simulations.

  • The monthly climatology files are in NetCDF format and can be downloaded from this website (Access restricted to CPT participants).


AMIP runs

CAM3 is forced with observed monthly mean SST and sea ice which change with time/years.

  • T42 AMIP (1979-1999)
  • Download data sets Model versus observations plots
  • T85 AMIP (1979-1999)
  • Download data sets Model versus observations plots

    SOM - Control

    CAM3 is coupled with a slab ocean model.

  • T42 SOM - Control
  • Download data sets Model versus observations plots
  • T85 SOM - Control
  • Download data sets Model versus observations plots

    SOM - 2xCO2

    CAM3 is coupled with a slab ocean model and an instantaneous doubling of CO2 is applied at the beginning of the integration.

  • Download data sets Model versus observations plots
  • T85 SOM - 2xCO2

    Observational data sets

    You can download the observational datasets used to compare with model data via our anonymous ftp site. The file is about 116 MB.
