Project Location: 
RMMA Broomfield, CO (KBJC)
Funding Type: 
NSF Funded
What's New?: 

Due to required maintenance on the NSF/NCAR C-130, SPICULE has been moved to the NSF/NCAR GV.  Some instrumentation has also changed including swapping the HIAPER Cloud Radar for the Wyoming Cloud Radar.

Project Description: 

The Secondary Production of Ice in Cumulus Experiment (SPICULE) will focus on airborne in situ and remote observations that provide intensive measurements of microphysical and dynamic parameters that may, or may not, support suspected Hallett-Mossop (HM) secondary ice process (SIP) in cumulus clouds. The PIs will use two airborne platforms, the NSF/NCAR GV working subcloud and warm regions of cloud, and the SPEC Learjet model 35A working the supercooled region of a cloud. The NSF/NCAR GV will be equipped with in situ microphysical probes, aerosol measurements of CCN, IFP and biological aerosols, air motion sensors and the HIAPER Cloud Radar (HCR). The SPEC Learjet will be equipped with state-of-the-art in situ microphysical probes, air motion sensing, and a Ka-band up/down radar.
