SimClim is our stand-alone modelling system that can be customised to examine risks from, and adaptations to, current climate variables and future climate change. Commonly used to build capacity for sustainability officers, policy makers, teachers, students, researchers and both non-governmental and governmental organisations.

What can you do with SimClim?

  • Spatial scenarios (user chosen year, emission scenario, climate sensitivity, and GCM)
  • Site specific scenario (given location, emission scenario, climate sensitivity, and GCM)
  • Site specific sea level rise (with/without vertical land movement)
  • Site data (import, browse, analytics)
  • Extreme events (analytics, with/without climate change)
  • Supports ensembles of GCMs

Highlights for SimCLIM Desktop 4.0

  • Ensembles: Ensembles are now easy to create as you use on the fly; you no longer need to create and manage "ensemble templates".
  • Overhauled the Site Specific SLR and Climate Scenario Generators with a new interface and functionality
  • Supports the new CLIMsystems License Manager, allowing for network license management for organizations.
  • Many other improvements throughout.

The SimClim for ArcGIS/Climate add-in enables ArcGIS users to produce spatial images of climate change through a quick, straight-forward process. The add-in is based on 20 years of development of the standalone SimClim tool and uses outputs from global climate models. Projections of future climate and changes compared with the baseline climate can be produced. Climate variables available on this application include:

  • precipitation (mm)
  • mean temperature (°C)
  • minimum temperature (°C)
  • maximum temperature (°C)
  • on request: solar (W/m2), relative humidity (%), wind (m/s)

The SimClim for ArcGIS/Marine add-in provides access to the AR5 marine results. It can help you explore the impacts of climate change on marine biogeochemical cycles, sea level, and sea surface temperature. It is a user-friendly ArcGIS Desktop application launched as a toolbar. It allows you to evaluate uncertainties of ocean warming, offering less time-consuming analysis, and optimizing research costs as well as enhancing current capacity. It has a unique sea level rise dataset, with seasonal variation, including vertical land movement. Functions available for the marine add-in include:

  • Spatial scenarios (given year, emission scenario, climate sensitivity, and GCM)
  • Ensembles on the fly
  • Percentile results for the ensembles
  • Extrapolated global coverage to simplify coast-line alignment
  • Minimum, average, and maximum over the months selected


SimClim is designed to support decision making and climate proofing in a wide range of situations where climate and climate change pose risk and uncertainty. A user customised SimClim Open Framework System software package has the capacity to assess baseline climates and current variability and extremes. Risks can be assessed both currently and in the future. Adaptation measures can be tested for present day conditions and under future scenarios of climate change and variability. With the program, users can conduct sensitivity analysis and examine sectoral impacts of climate change. SimClim supports integrated impact analysis at various scales.

A series of training videos are available on the SimClim website, including discussions on how to create ensembles of general circulation models, generate site-specific scenarios, and browse data.
