| Abstract: |
Values of undercatch-corrected liquid-equivalent snowfall rate (S) at a ground site and microwave reflectivity (Z) retrieved using an airborne W-band radar were acquired during overflights. The temperature at the ground site was between - 6 and - 15 ∘C. At flight level, within clouds containing ice and supercooled liquid water, the temperature was approximately 7 ∘C colder. Additionally, airborne measurements of snow particle imagery were acquired. The images demonstrate that most of the snow particles were rimed, at least at flight level. A relatively small set of S – Z pairs (four) is available from the overflights. Important distinctions between these measurements and those of Pokharel and Vali (2011), who reported S – Z pairs and an S – Z relationship for rimed snow particles, are (1) the fewer S – Z pairs, (2) the method used to acquire S , and (3) the altitude, relative to ground, of the W-band Z retrievals. This analysis corroborates the fact that the S – Z relationship reported in Pokharel and Vali (2011) yields an S – in scenarios with snowfall produced by riming – substantially larger than that derived using an S – Z relationship developed for unrimed snow particles.
