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

Table 1

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 radar, respectively.

(a)  

	Radar
Rain at buoy location (254 samples)	Correct ( > 0.1 mm/h and > 0 mm/h); 188 (72.83%)	Miss ( > 0.1 mm/h and = 0 mm/h); 69 (27.16%)
No rain at buoy location (6584 samples)	False alarm ( = 0 mm/h and > 0 mm/h); 61 (0.92%)	Correct ( = 0 mm/h and = 0 mm/h); 6523 (99.07%)

(b)  

	Radar
Rain at buoy location (117 samples)	Correct ( > 1 mm/h and > 0 mm/h); 99 (84.61%)	Miss (buoy > 1 mm/h and = 0 mm/h); 18 (15.33%)
No rain at buoy location (6721 samples)	False alarm (≤ 1 mm/h and > 0 mm/h); 147 (2.18%)	Correct ( ≤ 1 mm/h and = 0 mm/h); 6574 (97.81%)
