Try the water balance example

The working Constellarium lives on Weidu Fanling. Its tool catalogue lets you compare two fictional catchments. Run the hydrology calculation, read the ecology explanation, or inspect the assumptions and sources with the evidence audit. The catalogue works without navigating the globe.

Look at the evidence together

Try forming your own answer before comparing it with a tool’s result. Check the sources, write down where the answers differ, and keep uncertainty visible. The catchment tools are educational examples. The Commons portal itself has no live model connection.

When a project uses a language model, record its role, check its claims and have a person review anything that will be published. See the collaboration and reuse guide.

Find and review public tools

Conversation can start at The Hearth. The tool catalogue is a place to find examples, and the GitHub repository is where you can inspect the source, see changes or report an issue. A future catalogue could bring models, datasets and tools together with their sources, licences, test results and limits, so other people can decide what is useful to them.
