AIM/emission model estimates greenhouse gas emissions and assesses policy options to reduce them. AIM/climate model forecasts concentrations of greenhouse gases in the atmosphere and estimates the global mean temperature increase. AIM/impact model estimates climate change impacts on natural environment and socio-economy of the Asian-Pacific region.
The CCSM is a coupled climate model for simulating the earth’s climate system. Composed of four separate models simultaneously simulating the earth’s atmosphere, ocean, land surface and sea-ice, and one central coupler component.
The Cumulative Thread Model for the global ocean is model for simulating cumulative human impact on the ocean’s ecosystems and estimating the vulnerability of different marine ecosystems.
It is a global model for exploring the potential biodiversity impacts of human activities and environmental change under different policy scenarios. It is designed to support UNEP’s activities relating to environmental assessment.
The GUMBO is an exploration through simulation modeling into the global dynamics and interactions of the earth sociology, economy, and ecology. It represents the a synthesis and simplification of several existing global models to assess the dynamics and values of ecosystem services.
It is a coupled atmosphere-ocean general circulation model used for IPCC projections.
Earth System Grid II is a research project addressing the challenges associated with enabling analysis of and knowledge development from global Earth System models: create a virtual collaborative environment that links distributed centers, users, models, and data.
It is an atmospheric general circulation model.
To better understand ecological processes, and to evaluate their response to human activity IBIS simulates a wide variety of processes within the Earth’s terrestrial ecosystems.
This global modeling system aims to facilitate exploration of global futures through alternative scenarios. The model is integrated with a large database and represents the interacting demographic, economic, energy, agricultural, socio-political, and environmental subsystems within the global system.
LPJmL simulates vegetation composition and distribution as well as stocks and land-atmosphere exchange flows of carbon and water, for both natural and agricultural ecosystems at global level.
IMAGE is an ecological-environmental framework that simulates the environmental consequences of human activities worldwide. It represents interactions between society, the biosphere and the climate system to assess sustainability issues like climate change, biodiversity and human well-being.
The IMPACT model analyses the effects of population, investment, and trade scenarios on world crop and livestock commodities, and food security.
MIMES is a suite of models that evaluates land use changes and subsequent effects on ecosystem services on global, regional and local levels.
Messy provides a bottom-up modular approach to study the interactions between Earth’s bio-physico-chemical processes.
WaterGAP, a global model of water availability and water use, was developed to assess the current water resources situation and to estimate the impact of global change on the problem of water scarcity.
