Ice thickness is in inches, -1 = no thickness reported, see report for ice conditon codes.
T1 = ice thickness or part of a range if T2 is present, C1 = primary condtion of ice.
T1C1 = thickness of C1 or part of range if T2C1 is presnet.
C2, T1C2, T2C2, C3, T1C3, T2C3 are secondary and ternary ice conditon and condition thickness.
