Usage
This is the model that is used in the "Dutch Challenge Project". This project is
initiated in order to study the impact of a warming world on the occurences of
extreme weather events, such as extreme storms, hot and cold spells, droughts and such.
Version/resolution
In order to obtain at least 50 climate integrations of 140 years in the computing time
available, we have chosen version 1.4
at resolution T31, with modifications by the paleo group at NCAR to simulate reasonable
ENSO variability and include the effects of solar variations, Green House Gas changes and sulphate
and vulcanic aerosols on the
climate of the 20th century.
Description
The Community Climate System Model was designed by NCAR in the U.S.
It is a global climate model for simulating the earths climate system. Composed of four
separate model components simultaneously simulating the earths atmosphere, ocean,
land surface and sea-ice, and one central coupler component, the CSM allows
researchers to conduct fundamental research into the earths past, present and
future climate states.
Model components
| Name | Description | Version |
| atm | CSM1.4 Atmospheric model | CCM3.6.6 |
| ocn | CSM1.4 Ocean model | NCOM_1.5.0.BETA4 |
| ice | CSM1.4 Sea-ice model | CSIM2.2.9 |
| lnd | CSM1.4 Land-surface model | CCM3.6.6 |
| cpl | CSM1.4 Flux Coupler | CPL4.0.5 |
During the course of a CSM integration, each of the four component models integrate forward in time simultaneously, periodically stopping to exchange information with the coupler. The cpl receives state variables from the component models, computes the interfacial fluxes from this information and returns the flux information back to the component models. By brokering this sequence of communication interchanges, the cpl manages the overall time progression of the coupled model.
