English 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.
