This dataset is a standardized collection of ground temperature (GT) and ground surface temperature (GST) data from across Canada, designed to serve as a benchmark ensemble for synthesis and model evaluation. The collection integrates data from 29 published datasets and 11 unpublished contributions, encompassing 427 GT and 491 GST sites across British Columbia, Labrador, Northwest Territories, Nunavut, Québec, and Yukon.
All included time series have at least one year of measurements at daily resolution. We performed quality control and standardization using tempcf—a newly-developed python software tool—to document and remove anomalies, outliers, and drilling disturbances. Then we aggregated sub-daily data to daily means. The dataset is standardized into NetCDF files adhering to CF, ACDD, and IOOS metadata standards as well as compatible permafrost-specific metadata profile.
