“This study uses airborne profiling W-band Doppler radar data as well as in situ data. Cloud radars have a high sensitivity and fine spatial resolution. At mm- wave frequencies, the signal becomes attenuated in heavy precipitation, but this is not a problem for the typically light snowfall rates from orographic clouds. The nadir view (see Fig. 2 in Geerts et al., 2006) pro- vides radar data within ∼30 m of the ground, whereas the commonly used ground-based scanning radars can only “look” above the terrain peaks. The ability to look close to the terrain is important in the evalua- tion of ground-based seeding since the effect of seeding should be largely confined to the turbulent planetary boundary layer (PBL) (Geerts et al., 2011).” -p1026
