SimCLIM is a tool designed to support climate change decision making in a number of situations and sectors. The model allows for linking of user input data and models with global climate scenarios, and assessing various projected global changes and extreme event probabilities in the future, as well as current variability and extremes. The program allows for importing spatial and time-series data into a GIS viewer, and contains data from many different GCM runs and scenarios, such as SRES emissions scenarios.

Toolbox tags

This toolbox entry has been labelled with the following tags:

Sector: agriculture; health; coasts; water management
Spatial scale: independent
Temporal focus: present; future
Onset: independent
Role in decision process: diagnostic
Level of skills required: limited
Data requirements: modest
Adaptation tasks: Detection and attribution; Potential impact projection


As mentioned above, SimCLIM is able to be used to describe current climate baselines, variability, and extremes, as well as to generate and analyze future climate scenarios, assessing climate risks and adaptation options, and examining uncertainties. The GIS viewer allows for analysis at different spatial scales, from global to local, but uncertainties depend on both scenarios involved as well as the resolution of input data. There is also an ability to use location-specific tools to analyze time series point data and impact models. The key output of SimCLIM is the ability to analyze scenarios of climate and sea-level changes, as well as sectoral impacts, mainly for water, ecosystems, agriculture, health, and coastal zone issues.


While SimCLIM provides both observed climate data as well as GCM runs and scenario inputs, the model requires various inputs at either national or local scales, depending on the user's application goals. The program allows for importing of spatial and time-series data. The software itself is very accessible to use, and training sessions can be attended. There are no specific requirements for using the tool, however the program requires a license, which may be purchased on an individual basis.
