The earth system model LOVECLIM

ELIC Louvain-La-Neuve

Description

LOVECLIM is an acronym made from the names of the five different models that have been coupled to built the Earth system model: LOch–Vecode-Ecbilt-CLio-agIsm Model (LOVECLIM).

A list of papers using the model could be found here

  • Atmosphere: The atmospheric component is ECBILT (version 2) (Opsteegh et al., 1998)a global, spectral, quasi-geostrophic model, truncated at T21, with simple parameterisations for the diabatic heating due to radiative fluxes, the release of latent heat, and the exchange of sensible heat with the surface.
  • Ocean–sea ice: The CLIO model (Goosse and Fichefet, 1999) is made up of a primitive-equation, free-surface ocean general circulation model coupled to a thermodynamic–dynamic sea-ice model.
  • Vegetation: The terrestrial vegetation module developed by Brovkin et al. (1997) has been included in the coupled ECBILT-CLIO model. Based on annual mean values of several climatic variables, the VECODE model computes the evolution of the vegetation cover described as a fractional distribution of desert, tree, and grass in each land grid cell.
  • Ice sheets: ECBILT-CLIO-VECODE has been coupled to Huybrechts (2002)'s model, named AGISM (Antarctica and Greenland Ice-Sheet Model). It is a three dimensional thermomechanical model which simulates the ice flow, the bedrock evolution and the mass balance at the ice-sheet surface.
  • Carbon cycle: The terrestrial carbon cycle is simulated by VECODE. LOCH is a three-dimensional model of the oceanic carbon cycle developed by Mouchet et al. (1997).
