Overview

Norwegian Earth System Model

The Norwegian Earth System Model (NorESM) is one out of ~20 climate models that has produced output for the CMIP5 (http://cmip-pcmdi.llnl.gov/cmip5). The development of the NorESM started under the now finalized research project NorClim (http://www.norclim.no) and is continued as part of the ongoing EarthClim project (http://gfi.uib.no/EarthClim). EarthClim has eight partners: Uni Research AS (coordinator); 
Bjerknes Centre at the University of Bergen; CICERO Center for Intern Climate and Environmental Research; Norwegian Meteorological Institute; Department of Geosciences, University of Oslo; Norwegian Computing Center; Norwegian Institute for Air Research; and Norwegian Polar Institute, of which the Norwegian Meteorological Institute and the Bjerknes Centre have the main responsibility for the model development. The organizational framework for NorESM is the virtual Norwegian Climate Centre (NCC) consisting of nine of the ten institutions participating in EarthClim.

The NorESM-family of models are based on the Community Climate System Model version 4 (CCSM4) of the University Corporation for Atmospheric Research, but differs from the latter by, in particular, an isopycnic coordinate ocean model and advanced chemistry-aerosol-cloud-radiation interaction schemes. NorESM1-M has a horizontal resolution of approximately 2deg for the atmosphere and land components and 1deg for the ocean and ice components. NorESM is also available in a lower resolution version (NorESM1-L), a medium-low resolution version (NorESM1-ML), a high-top version with specified and full chemistry (NorESM1-MLHT and NorESM1-MLHTC) and a version that includes prognostic biogeochemical cycling (NorESM1-ME).
