MAGICC and SCENGEN is a package of two tools distributed by a researcher at UCAR; MAGICC is a gas cycle and climate model which has been used to make projections of future global temperatures and sea level change, based on chosen emission scenarios. SCENGEN allows for downscaling of the MAGICC outputs to a regional level.
This toolbox entry has been labelled with the following tags:
| Sector: | global context; climate | |
| Spatial scale: | global; regional | |
| Temporal focus: | future | |
| Onset: | slow | |
| Role in decision process: | diagnostic | |
| Level of skills required: | modest | |
| Data requirements: | high | |
| Adaptation tasks: | Potential impact projection; Detection and attribution |
The set of models are applicable in any analysis of future composition of the atmosphere, climate, or sea level. SCENGEN allows for the results to be output at a 5 degree square grid, allowing for global and more regional, but still large scale, analysis.
The tools are provided free to use by the developer; the only requirements are a computer, and a user's manual is provided to explain use of the tools. SRES scenario inputs are required to drive MAGICC.
The primary developer, Tom Wigley, can be contacted at wigley@ucar.edu.

Historical climate analysis and climate projections for Burundi
This climate analysis was conducted as part of the DFID-funded Economics of Climate Change on East Africa project. The Inter-Tropical Convergence Zone (ITCZ) weather system dominates Burundi's climate. It drives a bi-modal seasonality, with the main rain events occurring March-May and October-November as the ITCZ migrates southward... |
