Figure 2.

Box-plots (i.e., 5^th, 25^th, 50^th, 75^th and 95^th percentiles) of storm-scale runoff ratio versus: a) total storm rainfall accumulation depths [mm] and b) pre-storm surface soil moisture [m³m⁻³] for storm events observed across all basins in Figure 1. In part b), pre-storm surface soil moisture is based on SMAP_L4 surface soil moisture estimates and events with accumulation depths less than 10 mm are excluded. Numbers represent total storm events described by each box-plot. Runoff ratios greater than one likely reflect measurement errors in estimates of storm total rainfall and/or stream flow used to determine the storm runoff ratio.
