snow-phenology-data

This dataset supports the paper “Increased Sensitivity of Snow Phenology to Temperature in Unstable Snow Regions Since 1990.” It includes processed observational and reanalysis data used to extract snow phenology metrics and generate all tables and figures in the study. The data are organized as follows: 1、Snow Phenology Calculation.zipProcessed GHCN station-level snow depth data used for snow phenology extraction. Missing dates are marked as "NA". Each file corresponds to one station. 2、Process meteorological data.zipMeteorological data (temperature and precipitation) used to fill missing values in the original records using ERA5 reanalysis data. ERA5_T_daily_℃: Daily temperature from ERA5 ERA5_P_mm: Daily precipitation from ERA5 Combined_Results: Final filled and filtered dataset (200 stations) used for snow phenology extraction and further analysis (also found in Fig3_5_6_8 and Table1.zip). 3、Fig1.zipData used to generate Figure 1, based on extracted snow phenology metrics. 4、Table2.xlsxIntegrated snow phenology and meteorological data for the 200 selected stations. Used to produce Table 2. 5、Fig2.zipSummary data derived from Table2.xlsx, used to produce Figure 2. 6、Fig3_5_6_8 and Table1.zipCore dataset of 200 stations with extracted snow phenology and meteorological variables. Used to generate Figures 3, 5, 6, 8 and compute slope and p-values reported in Table 1. These are the same as the Combined_Results from Process meteorological data.zip. 7、Fig4.zip and Fig7.zipResults from trend analyses based on Table1.py (1st and 2nd sections), used to generate Figures 4 and 7. All data files are provided in ready-to-use formats and correspond directly to the figures and tables presented in the manuscript.
