To reduce the uncertainty of using the single-algorithm, or single-climate-model approach to investigating climate change impacts on biodiversity, you can run an ensemble experiment. You can run several different species distribution models for one species when assessing the distribution under current climate, or use several general circulation models in a climate change projection. The outputs of these can then be used in an Ensemble Experiment.

Step 1. Description tab

• Enter the name for your experiment in the first box (e.g. Ensemble Fox (Vulpes vulpes) Distribution)
• (optional) You can also add a description of your experiment in the box below if you want to convey more information. Some researchers use this box to record their research question or hypotheses for later referral
• Click Next.

Step 2. Source Data tab

• Click on the drop-down box under Select Experiment Type.
• Here you have two options: SDM Experiment or Climate Change Experiment. Select the experiment type you want to run your Ensemble on. 
• Click on Select Experiment.
• In the pop-up box choose one of the corresponding previously run experiments and click Select Experiment. You can select multiple experiments as well.
• Select the models within the experiment with which you want to use in the Ensemble Analysis.
• Click Next.

Step 3. Run tab

• Ensure you are happy with your experiment design.
• If all tabs are green then your experiment is ready to go.
• Click Start Experiment.
• If any of your tabs are red, revisit it and ensure you have filled in each component correctly.

A log file will now be sent to our virtual machines where your experiment will be run. You will receive an email when your results are ready to view. This can be done from the Experiments page. For now, sit back and relax, grab a coffee, or do some other work without being hampered by a slower computer that is running heavy models in the background.
