Abstract

In this report we lay the scientific and numerical basis for a two- dimensional Energy Balance Model (EBM) to be integrated into the climate module of IMAGE (the Integrated Model to Assess the Greenhouse Effect) developed at RIVM. This EBM will calculate regional projections of surface temperature, resolved with respect to latitude and height based on emission scenarios. Although our EBM-model is still simple - no distinction is yet made between land, atmosphere and ocean and, also, a deep ocean is not corporated - its implementation is an important step in the modeling hierarchy, which leads to a regionalized climate module within IMAGE. This module can be used as a tool for integrating IMAGE with environmental impact models, which than can run in a time-dependent mode.
