The Climatch algorithms - A complement to the Climatch user manual

Climatch is a software tool used to assess the climate suitability of a particular environment for a given species. It is widely used in environmental research, particularly for assessing the establishment risk of invasive species. This report complements the existing Climatch user manual by offering an in-depth explanation of the Euclidean and Closest Standard Score algorithms. It provides a detailed, step-by-step comparison of the two methods using a small artificial dataset to demonstrate their application. This report also includes some guidance for users on selecting between the two algorithms and discusses additional considerations when using climate matching software.
