Global Climate Modeling

Main content

Global climate modeling (GCM) activities at C2SM are centered around the global climate model ECHAM and the Community Earth System Model.

ECHAM-HAMMOZ is a fully coupled climate-aerosol-chemistry model that is hosted and maintened at ETH Zurich.ECHAM is a climate model developed and maintained by the Max Plank Institute for Meteorology (MPI-M) in Hamburg. It corresponds to the atmospheric component of the MPI Earth system model (MPI-ESM). Over the years, several groups in the European research community have contributed to couple ECHAM and MPI-ESM to complementary modules to represent specific components and processes of the Earth climate system. In particular, a sub-module for aerosol (HAM) and a sub-module for trace gas chemistry (MOZ) have been coupled to ECHAM and MPI-ESM, leading to the formation of the ECHAM-HAMMOZ and MPI-ESM-HAMMOZ.

Since 2009, C2SM Member Ulrike Lohamnn is the chairman of the HAMMOZ consortium that includes Max Plank Institute for Meteorology, the Forschungszentrum Jülich, University of Oxford, Finnish Meteorological Institute, ETH, and C2SM. C2SM provides support for the maintenance and hosting the ECHAM-HAMMOZ and MPI-ESM-HAMMOZ models at ETH.

We are also working towards the integration of the next generartion of climate models developed at MPI-M, that is, the ICON (Icosahedral non-hydrostatic) climate model.

Community Earth System Model (CESM)

The CESM (Community Earth System Model) is a fully-coupled, community, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states. It consisits of 6 separate models simultaneously simulating the Earth's atmosphere, ocean, land, land-ice, sea-ice, river runoff and ocean wave, plus one central coupler component.

The CESM model can be configured in a number of different ways from both a science and technical perspective. CESM supports several different resolutions and component configurations.

CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Division (CGD) at the National Center for Atmospheric Research (NCAR).
