AB: Airborne radar measurements are combined with flight-level particle and temperature measurements to gain insight in the growth of precipitation particles as air crosses a mountain range. The radar is a 3 mm Doppler radar (the Wyoming Cloud Radar) operating with fixed antennas both in the zenith and the nadir, thus providing reflectivity and vertical velocity profiles above and below the aircraft (which is centered in a 200 m deep blind zone). The aircraft, the Wyoming King Air, carries various particle probes (2D-P, 1D-P, 1D-C, and FSSP). The plan is for the aircraft to conduct several flight legs across an elongated mountain range in Wyoming during the passage of frontal systems in the winter of 2005-06. Cross sections across the mountain range will be presented, showing reflectivity and particle vertical motion. Snowrate and snow habit measurements will be conducted at the ground on top of the mountain range.
