Flights do not have all measurements due to instrument
issues.
●
Use Cloud Droplet Probe (CDP) droplet spectrum
measurement, instead of the Hawkeye-FCDP measurement.
●
FCDP seems to have shattering issues (working on).
●
Use the King Probe liquid water content (LWC)
measurement, instead of the WCM LWC measurement
(working on WCM processing improvements).
●
Work with IMPACTS personnel when using cloud probe
measurements.

Research conducted in IMPACTS 2022 focused on analyzing data from cloud probes installed on P-3 aircraft. The study included measurements of water content, droplets, and comparisons between different probe systems. Flights encountered challenges with instrument issues affecting data collection. Detailed investigations and findings are presented, shedding light on atmospheric phenomena.

WCM and King Probe Comparison (>0.005 g/m3) WCM = 0.54*King + 0.012 Correlation = 0.66
Conclusions Flights do not have all measurements due to instrument issues. Use Cloud Droplet Probe (CDP) droplet spectrum measurement, instead of the Hawkeye-FCDP measurement. FCDP seems to have shattering issues (working on). Use the King Probe liquid water content (LWC) measurement, instead of the WCM LWC measurement (working on WCM processing improvements). Work with IMPACTS personnel when using cloud probe measurements.
