Figure 2.

Figure 2 is a set of nine dot graphs titled Miami−Dade, Florida (storms: 57; monitors: 12), Harris County, Texas (storms: 34; monitors: 17), Mobile County, Alabama (storms: 49; monitors: 7, Orleans Parish, Louisiana (storms: 50; monitors: 6), Fulton County, Georgia (storms: 43; monitors: 5), Charleston County, South Carolina (storms: 67; monitors: 7), Wake County, North Carolina (storms: 58; monitors: 10), Baltimore County, Maryland (storms: 32; monitors: 3), and Philadelphia County, Pennsylvania (storms: 50; monitors: 3), depicting the comparison between the two sources of storm-associated rainfall: county-level estimates derived from a re-analysis data set and county- level estimates based on ground-based observations in nine sample counties by plotting Rainfall (millimeters) from monitors, ranging from 0 to 200 in increments of 100; 0 to 200 in increments of 100; 0 to 600 in increments of 200; 0 to 300 in increments of 100; 0 to 150 in increments of 50; 0 to 200 in increments of 50; 0 to 200 in increments of 50; 0 to 100 in increments of 50; and 0 to 150 in increments of 50 (y-axis) across Rainfall (millimeter) from North American Land Data Assimilation System Phase 2 data, ranging from 0 to 200 in increments of 100; 0 to 200 in increments of 100; 0 to 600 in increments of 200; 0 to 300 in increments of 100; 0 to 150 in increments of 50; 0 to 200 in increments of 50, 0 to 200 in increments of 50; 0 to 100 in increments of 50; and 0 to 150 in increments of 50 (x-axis) for Spearman’s Rho, including 0.93, 0.92, 0.95, 0.87, 0.95, 0.94, 0.98, 0.94, and 0.96, respectively.

Comparison in nine sample counties of two sources of storm-associated rainfall estimates: (A) county-level estimates derived from a reanalysis data set and (B) county-level estimates based on ground-based observations in nine sample counties. For both, estimates include rainfall from 2 d before to 1 d after the storm’s closest approach to the county. Each small graph shows data for one sample county, and each point shows one tropical storm. The number of storms within each county and the number of ground-based monitors reporting precipitation during the county’s storms are given above each plot. Horizontal and vertical lines in each plot show the threshold of 75mm used to classify a storm as “exposed” for the binary classification considered for this metric in further analysis (Table 1). Note that ranges of the x and y axes differ across counties.
