Scenario Set Generator

When you start SimCLIM 4.x for Desktop , you can choose scenario set from the toolbar at the top of the screen

or by right clicking within the main window and clicking on the scenario set icon.

With the new scenario set window open you can consider your many options for rapidly generating multiple scenarios of climate change. The variables include: areas, climate variables, year range, month range, GCM patterns, greenhouse gas projections, synthetic outputs options and file saving, either Idrisi image or ArcView ASCII.


In this activity you will generate a set of scenario options and view some of them within the SimCLIM 4.x for Desktop software system.

You will do this for a range of variables and outputs, including synthetic model results. Click on the scenario set icon and explore the window. We will now explore each of the nine areas within the scenario select window prior to running a set.. You can open most boxes by clicking on the arrow at the left side of the variable box .

For example the GHG Concentration Pathways when the arrow is clicked for it expands to the following:

Now you can systematically go through each of the nine parameters before running a scenario set for your study area.

By clicking on the areas arrow and then the Global icon in the left window your available study areas will be displayed:

Highlight the area and click add if you wish to include it in your analysis. Do this for each area you wish to include. Experiment with this process of adding and removing areas so you can become comfortable with the process.

Click on the arrow beside Years:

Type in the years your interested in. For example 2050, 2070, 2100 with a comma between each year. Be careful not to choose too many years as depending on the other options chosen you could generate thousands of map outputs.

Click on the arrow beside Months:

Click on the individual month(s) of interest or select all for annual and Add to move them to the active box on the right.

Click on the arrow beside Climate Variables:

Click the boxes of the variables you are interested in including in your scenario set run.

Click on the arrow beside Patterns:

Select the individual patterns you are interested in running. Leave this dialogue box if you are going to apply an ensemble(s).

Click on the arrow beside Ensembles:

Click on the Ensemble(s) of interest for your scenario set run and choose a number for your low and high percentile if you are interested in probability of high or low outcomes.

Click on the arrow beside the Greenhouse Concentration Pathways (RCPS):

Select the RCP(s) of interest and the sensitivity you wish to apply.

Click on the arrow to beside the Synthetic Scenario if you are running one:

Click on the arrow beside Output:

Choose the type of output you are interested in and the folder where they should be generated.

You are now ready to run your scenario set. If you wish to use the set up again or wish to only change one or two variables but leave most of the paramaters again it is suggested that you save the set up by clicking on save on the bottom toolbar:

An option for naming the set up will be provided.

You will click on the load button to load a saved set in the future.

Click OK to run your analysis.

Setting up the scenarios set options can be complicated. The tool will provide you with a list of errors if when you click on OK there are any problems with the set up. An example is found below:

Go back and fix these oversights and click on OK again and hopefully you are successful.

If you are successful the following dialogue box will be displayed:

Click on View Report for more information:

If you wish to view the actual images produced then you can right click in the main SimCLIM window and choose open image to display the files. You will be asked to browse the the folder where you asked to have the files saved.

Click on a file and click on Open.

You can then click on OK and open the file:
