Underwater Acoustic Measurements to Estimate Wind and Rainfall in the Mediterranean Sea

Table 2

Contingency table for the thresholds of (a) 0.1 mm/h and (b) 1 mm/h. and are the hourly cumulative rainfall measured by the rain gauge installed on the “ODAS Italia 1” buoy and estimated by PAL, respectively.

(a)

	PAL
Rain at buoy location (286 samples)	Correct ( > 0.1 mm/h and > 0 mm/h); 167 (58.39%)	Miss ( > 0.1 mm/h and = 0 mm/h); 119 (41.61%)
No rain at buoy location (7569 samples)	False alarm ( = 0 mm/h and > 0 mm/h); 40 (0.52%)	Correct ( = 0 mm/h and = 0 mm/h); 7529 (99.48%)

(b)

	PAL
Rain at buoy location (137 samples)	Correct ( > 1 mm/h & > 0 mm/h); 115 (83.94%)	Miss ( > 1 mm/h & = 0 mm/h); 22 (16.06%)
No rain at buoy location (7718 samples)	False alarm ( ≤ 1 mm/h and > 0 mm/h); 92 (1.19%)	Correct ( ≤ 1 mm/h and = 0 mm/h); 7626 (98.81%)
