Characterization of a 3D printed pumped counterflow virtual impactor and an aerodynamic lens concentrator
… cloud sampling devices, the pumped counterflow virtual impactor (PCVI) and aerodynamic lens concentrator (ADL), were modelled using computer aided design software and printed using stereolithography printing. These devices were compared against their industrial counterparts. The printed PCVI was …

The phase separation inlet for droplets, ice residuals, and interstitial aerosols
… inlet, a Large-Pumped Counterflow Virtual Impactor (L-PCVI), a flow tube as evaporation chamber, and a Pumped Counterflow Virtual Impactor (PCVI) to separate droplets, ice crystals, and interstitial aerosols for simultaneous sampling. Verification tests of each individual component …

In situ and satellite-based estimates of aerosol-cloud interactions between biomass burning aerosols and marine stratocumulus clouds over the southeast Atlantic Ocean
… in-cloud aerosol samples from the counterflow virtual impactor inlet to examine the extent of entrainment mixing of aerosols into the cloud layer. Modeling studies should examine the impact of precipitation suppression on cloud lifetime and boundary layer dynamics. Model parameterizations of Rp …

Development of a semivolatile aerosol dichotomous sampler
… filter sampling. The main difference between virtual impactors and the SADS was the inverted flow ratio between the major and the minor flow. Sampling in the SADS settings gave a lower cutsize in both numerical simulations and experimental results. The second section reports the results of an …
