clear sky ice crystal precipitation and light ice precipitation under overcast sky conditions produced volume backscatter coefficients in the 2-4 x 10 ( -3 ) -km ( -1 ) range and depolarization values up to 0.46 , while mixed phase and supercooled water drop layers were also observed with maximum backscatter coefficients ranging from 5 x 10 ( -2 ) to 2.4 x 10 ( -1 ) km ( -1 ) and depolarization values from a few to ~20 % .
