title: Climate warming drives rockfall from increasingly unstable mountain slopes

description: The datasets and R codes provided here were used for the analysis of changes in and drivers of rockfall activity over time at Täschgufer (Valais, Swiss Alps), using rockfall damage in European larch (Larix decidua Mill.). This readme file provides all raw data and R codes used to perform the analyses presented in Figs. 2-4 of the main text and Supplementary Information Figures S1-S2. <br> FIGURE 2<br> -- Rockfall_Seasonality.txt: Contains information on the timing of rockfall rockfall (Season) in a given tree (Id) and a given year (yr) over the past 100 years. "Quality" refers to day of year (DOI) to which rockfall was assigned using a Monte Carlo resampling approach.<br> -- Trends_in_Seasonality.R: The data contained in "Rockfall_Seasonality.txt" were processed with the R script "Trends_in_Seasonality.R".This seasonal trend analysis code is inspired by work published by Heiser et al. (2022; https://doi.org/10.1029/2011JF002262). <br> FIGURE 3<br> - Rockfall_Impact_Dataset.txt: Contains the raw data on rockfall impacts (GD) in a given year (yr) as found all trees available in that same year (Sample_depth) as well as the cumulated diameter at breast height (cumulated_DBH) of all trees present in that same year.<br> - RCI_processing.R: The data contained in "Rockfall_Impact_Dataset.txt" were processed with the R script "RCI_processing.R".<br> - The temperature data used in Fig. 3 are from the E-OBS datasets: https://surfobs.climate.copernicus.eu/dataaccess/access_eobs.php <br> FIGURE 4<br> - Rockfall_Impact_Dataset.txt: Contains the raw data on rockfall impacts (GD) in a given year (yr) as found all trees available in that same year (Sample_depth) as well as the cumulated diameter at breast height (cumulated_DBH) of all trees present in that same year.<br> - Rockfall_Climate_Relations.R: The data contained in "Rockfall_Impact_Dataset.txt" were processed with the R script "Rockfall_Climate_Relations.R".<br> - The temperature data used in Fig. 4 are from the E-OBS datasets: https://surfobs.climate.copernicus.eu/dataaccess/access_eobs.php <br> FIGURE S1<br> - Rockfall_Impact_Dataset.txt: Contains the raw data on rockfall impacts (GD) in a given year (yr) as found all trees available in that same year (Sample_depth) as well as the cumulated diameter at breast height (cumulated_DBH) of all trees present in that same year.<br> - Rockfall_Climate_Relations.R: The data contained in "Rockfall_Impact_Dataset.txt" were processed with the R script "Rockfall_Climate_Relations.R".<br> - The precipitation data used in Fig. S1 are from the E-OBS datasets: https://surfobs.climate.copernicus.eu/dataaccess/access_eobs.php FIGURE S2<br> - Rockfall_Impact_Dataset.txt: Contains the raw data on rockfall impacts (GD) in a given year (yr) as found all trees available in that same year (Sample_depth) as well as the cumulated diameter at breast height (cumulated_DBH) of all trees present in that same year.<br> - Rockfall_Climate_Relations.R: The data contained in "Rockfall_Impact_Dataset.txt" were processed with the R script "Rockfall_Climate_Relations.R".<br> - The permafrost borehole temperatures (at 0.6 m depth) of Corvatsch were downloaded from the Swiss Permafrost Monitoring Network (PERMOS) website:
