Figure S1. Leftmost scatterplot (a) illustrates the relationships between β_FC and β_{precipitation} for each station colored by the station's associated SGA letter. The top right scatterplots (b) illustrate β_FC and β_{precipitation} for each station within the SGA. The lower right histograms (c) show the distributions of β_{precipitation} values broken down by SGA letter. Both (b) and (c) further demonstrate the spatial variation in precipitation trends and relationships between β_FC and β_{precipitation} across the coast.
