Durango Radar Experiment 2010

The goals of this project are to demonstrate the gap-filling potential of a small Doppler radar within the coverage area of the National Weather Service WSR-88D radar at Grand Junction and examine the terrain-induced circulations favorable for storm formation and motion. The NSSL's mobile operational polarimetric X-band Doppler radar NOXP together with a large number of microphysical surface observation instruments (NCAR's rain gauges, CU's disdrometers, CU's microwave rain radar, NCAR's surface mesonet stations) were deployed in the vicinity of Durango, CO between July and August 2010. The radar was operated at the Durango airport, disdrometers and MRR were deployed at the Fort Lewis College in Durango (Figs. 2-5), and rain and rivergauges were deployed within the vicinity (see Fig. 1). Data collection at the various sites will provide insight into the variations of storm characteristics for different terrain profiles.
