IMAGE 2.0

Another team of researchers from RIVM, the Dutch Institute for Environment and Public Health, has developed IMAGE 2.0 (Integrated Model to Assess the Greenhouse Effect). Though sharing a name with IMAGE 1.0, IMAGE 2.0 differs in several fundamental respects. In particular, IMAGE 2.0 is the first integrated assessment model to represent environmental phenomena at a fine spatial scale. IMAGE 2.0 consists of energy-industry, terrestrial environment, and atmosphere-ocean submodels.

The energy-industry model is based on highly detailed bottom-up regional representation of technologies and their emission characteristics in 13 world regions, with very little modeling of behavior. The terrestrial environment model represents land-use, soil type, element fluxes and certain classes of impacts and land-use change on a world-wide grid at 0.5-degree resolution, and permits vivid high resolution display of emissions, land use, and certain impacts on global maps. The atmosphere-ocean module uses a two-dimensional atmospheric energy model and a separate two-dimensional ocean model. The computational demands of all these models are large, yielding run times from several hours to a day. Consequently, the uncertainty analysis performed with them is limited to comparison of large discrete policy futures or scenarios (Alcamo et al. 1994a and 1994b). An outline of model design and results from four scenario runs are documented in Alcamo et. al (1994a); policy runs are summarized in Alcamo, Krol, and Leemans (1995).
