Description

Long-term phenological data in alpine regions are often limited to a few locations and thus, little is known about climate-change induced plant phenologica...

Resources

  • all_stations.csv

    Contains unfiltered annual phenological, temperature and snow-climatic data for all IMIS stations.

    all_stations.csv

  • IMIS_daily.csv

    Contains daily climate station data including daily median temperatures, snow depth, plant height, and annual melt-out timings.

    IMIS_daily.csv

  • pheno_params.csv

    Contains annual phenological variables and phenofit outputs, sorted, ordered and renamed according with the readme in this repository

    pheno_params.csv

  • phenofit_outputlist.rds

    Temporary data. Contains annual unfiltered output of phenofit (i.e. the variable names are in line with the phenofit documentation), including all curve parametrization variables for plotting and additional variables, which are not necessarily used in the analysis.

    phenofit_outputlist.rds

  • phenostations.csv

    Contains filtered annual phenological data from 40 IMIS stations suitable and used for phenological analysis

    phenostations.csv

  • station_info.csv

    Contains IMIS station location data

    station_info.csv

  • 0_readme.Rmd

    Is the readme that documents all data and code in this repository

    0_readme.Rmd

  • 1_phenofit.R

    implements the phenofit method. Note: This script is computationally intensive and may take a while to run. We recommend using the temporary data created from it (i.e. starting from 2_temperature.R). For a better description of the phenofit R package and the different methods to determine the SOG, see Kong et al. (2022): https://doi.org/10.1111/2041-210X.13870

    1_phenofit.R

  • 2_temperature.R

    Contains temperature-related calculations.

    2_temperature.R

  • 3_models.Rmd

    Documents and reproduces the statistical models used in the analysis.

    3_models.Rmd

  • 4_functions.R

    Contains custom functions required for the scripts; this file must be sourced before running other scripts.

    4_functions.R

  • 5_method_plots.Rmd

    Generates the methods-related figures used in the publication.

  • grass.png

    Snow3.png and grass.png are needed for plotting the methods plot in 5_methods_plots.Rmd
