Acadia National Park driest month with 3.3" (84 mm). Precipitation days are spread evenly throughout the year with January averaging the most days, about 11, while August averages the least, about 8, and all other months average 9 or 10 days. The annual average days with precipitation is 115 which consists of about 82 rainy days and about 33 days with frozen, or freezing, precipitation (snow, sleet, hail, freezing rain, or combinations). Snow has been recorded from October to May though the majority falls from December to March. The snowiest month is February with 18.7" (47.5 cm), and the annual average is 66.8"
Backscatter diameter of the target multiplied by its inherent reflective properties, provided the wavelength is larger than the particle diameter (Rayleigh scattering). Water is almost 4 times more reflective than ice but droplets are much smaller than snow flakes or hail stones. So the backscattering is dependent on a mix of these two factors. The strongest backscatter comes from hail and large graupel (solid ice) due to their sizes, but non-Rayleigh (Mie scattering) effects can confuse interpretation. Another strong return is from melting snow or wet sleet, as they combine size and water reflectivity. They often show up as much higher
