Data sets
A standardized permafrost ground temperature collection for Canada 2025 Olivia Meier-Legault et al. https://doi.org/10.5281/zenodo.18022924
Short summary
Ground temperature data is vital for permafrost and climate research yet data is often fragmented. We created a standardized collection of ground temperatures from over 900 sites across Canada. From 42 published and unpublished sources, we manually verified, cleaned and standardized data with a new software tool. This dataset supports permafrost research on a nationwide scale and can help improve models by acting as a reliable benchmark.
