NRC Convair 580 Aerosol Data

The list includes a Condensation Particle Counter (CPC), Ultra-High Sensitivity Aerosol Spectrometer (UHSAS), Single Particle Soot Photometer (SP2), and a Cloud Condensation Nuclei counter (CCNc), which were installed in the aircraft cabin to sample via an isokinetic inlet installed on top of the fuselage.

In addition, NRC wing tip mounted UHSAS was installed and sampled throughout the whole campaign. Due to the nature of Intensive Operational Periods (IOP)s, most of the flight time in the domain was spent in-cloud or in precipitation with the associated risk of flooding the cabin aerosol instruments, which led to the suspension of aerosol sampling. To address this issue, towards the latter portion of the campaign, starting from IOP7, a Counter-flow Virtual Impactor (CVI) inlet system was integrated on the fuselage starboard side window, for the first time.
