  • Nucleus for European Modelling (NEMO)
    NEMO (Nucleus for European Modelling of the Ocean) is a state-of-the-art modeling framework for oceanographic research, operational oceanography seasonal forecast and climate studies. NEMO is used by a large community: 240 projects in 27 countries (14 in Europe, 13 elsewhere), 350 registered users (numbers for year 2008). NEMO is available under CeCILL license (public license).

  • Paleoclimate Modelling Intercomparison Project (PMIP)
    The Paleoclimate Modelling Intercomparison Project was a project to coordinate and encourage the systematic study of atmospheric general circulation models (AGCMs) and to assess their ability to simulate large climate changes such as those that occurred in the distant past. Project goals included identifying common responses of AGCMs to imposed paleoclimate "boundary conditions," understanding the differences in model responses, comparing model results with paleoclimate data, and providing AGCM results for use in helping in the analysis and interpretation of paleoclimate data. PMIP initially focused on the mid-Holocene (6,000 years before present) and the Last Glacial Maximum (21,000 yr BP). One of the goals of PMIP was to determine which scientific results are model-dependent. The PMIP experiments were limited to studying the equilibrium response of the atmosphere (and such surface characteristics as snow cover) to changes in boundary conditions (e.g., insolation, ice-sheet distribution, CO2).
  • Paleoclimate Modelling Intercomparison Project - Phase 2 (PMIP2)
    PMIP 2 continued to stimulate development and improvement of paleo-environmental data sets. As in PMIP 1, analyses focused on both model-model and model-data comparisons. The project studied the role of climate feedbacks arising for the different climate subsystems (atmosphere, ocean, land surface, sea ice and land ice) and evaluated the capability of state of the art climate models to reproduce climate states that are radically different from those of today. Results from both coupled ocean-atmosphere models and ocean-atmosphere-vegetation models were considered in this second phase.
  • Coupled Model Intercomparison Project (CIMP)
    Started in 1995, CMIP provides a community-based infrastructure in support of climate model diagnosis, validation, intercomparison, documentation and data access.
