Dataset: Water flow timing, quantity, and sources in a fractured high mountain permafrost rock wall

This dataset contains hydrological and thermal time series used in the study “Water flow timing, quantity, and sources in a fractured high mountain permafrost rock wall”. The data were collected at the Aiguille du Midi site (Mont Blanc massif, French Alps) and include measurements of air temperature, ground surface temperature, rock temperature within fractures, tunnel air temperature, and water temperature, along with discharge estimates and derived variables. The dataset covers the monitoring periods analyzed in the manuscript and is provided as processed time series derived from field sensors installed within and around a permafrost-affected fractured rock wall. Data processing steps include temporal aggregation, quality control, and removal of erroneous or missing measurements. These data support the analysis of the timing, magnitude, and thermal controls of water flow in fractured permafrost environments, and can be used for further studies on mountain hydrology, heat transfer, and rock slope stability. All variables are documented within the files, including units and variable names. A README file is included to describe the dataset structure and processing workflow.
