LIST of available DATA and brief description

1. TREND results
FILES: 
./Pepin20_gridded_T_native.txt
./Pepin20_gridded_PR_native.txt

WHAT: Results of the temperature (T) and precipitation (PR) 
      trend analysis for different datasets, periods and 
      bands/regions as reported in the tables and figures 
      of the manuscript.

      The files report:
      "Dataset region period target trend pvalue level-of-significance (number) level-of-significance (symbols: *=0.05, **=0.01)
 
      Target can be k1, lowland or k1-lowland difference (k1-ll-diff)
      
      Example:
      "ERA5 Tibet 1900-2018 k1 3.20 0.000 0.01 **" 


2. Montecarlo test on parameter sensitivity
FILE: ./montecarlo_ERA5.dat

WHAT: Results of the parameter sensitivy analysis performed on ERA5
      temperatures as indication of uncertainty on the trends. 
      The file reports the mean and standard deviation of the ensemble 
      of 19 sets of trends obtained over 1980-2018 with various configurations 
      of the parameters of the analysis (top two blocks) and the trends of each
      configuration (following 19 blocks).
      
      The file reports:
      - Top two blocks (MEAN and ST.DEV of ensemble):
        "Region k1-trend ll-trend diff-trend k1-pvalue ll-pvalue diff-pvalue number-of-significant-cases-in-ensemble

         Example: "Rockies  3.69  2.36  1.32  0.00  0.03  0.05   10"

      - Following 19 blocks (OUTPUT/name-of-ensemble-member):
        "Region k1-trend ll-trend diff-trend k1-pvalue ll-pvalue diff-pvalue significance-of-the-trend-of-the-difference (*=0.05, **=0.01)
       
         Example: " Rockies  3.66  2.45  1.21  0.00  0.02  0.04    *"

3. CMIP5 ensemble means
FILES:
./raw-results/tas_Amon_ENSMEAN_historical_r1i1p1_1900-2005_1deg_anomaly_base1986-2005.nc
./raw-results/tas_Amon_ENSSTD_historical_r1i1p1_1900-2005_1deg_anomaly_base1986-2005.nc
./raw-results/pr_Amon_ENSMEAN_historical_r1i1p1_1900-2005_1deg_anomaly_base1986-2005.nc
./raw-results/pr_Amon_ENSSTD_historical_r1i1p1_1900-2005_1deg_anomaly_base1986-2005.nc

WHAT: Results of the ensemble mean and standard deviation for tempertaure and precipitation stored
      as self-explanatory NetCDF files. Ensemble data were produced using the models listed 
      in table S1 of the supplementary material.      

4. Timeseries and other intermediate files
FILES:
./raw-data/Pepin2020_T_native/*
./raw-data/Pepin2020_PR_native/* 

WHAT: These two folders contain the timeseries obtained for each dataset, period, 
      and target (k1, lowland or k1-lowland difference) and further intermediate files 
      produced during the analysis. Results were obtained both on annual base and 
      individual seasons. They are made available during revision for transparancy 
      but will NOT be made publicly available afterwards.
     
5. Original datasets 
They can be reached through their public repositories as listed in the manuscript.
