Descriptive overview of groundwater data and selected Earth system variables contained in GROW. (a) The map displays the locations of all time series, classified by temporal resolution. The color indicates whether a time series has a daily (orange), monthly (green) or yearly (purple) resolution. (b) Additionally, the 25% percentile, 50% percentile and 75% percentile of the median depth to groundwater per well and the percentage of wells with a median groundwater depth above 100 m is given for each temporal resolution. Below, (c) the number of time series available per year, and (d) the number of time series per length class in years are displayed. At the bottom, the distributions of selected Earth system variables in GROW compared to their respective global distributions are shown. The stacked bar charts show (e) the fraction of grouped Koeppen-Geiger climate classes and (f) the fraction of main land uses in GROW.
