Clarke Inlet
Clarke aerosol inlet mounted on side of C130. This inlet design is better suited than HIMIL for instrument requiring sample flow rates larger than a few liters per minute, or for sampling particles larger than 1 micrometer.
CVI Out
Exterior view of external sampling port on C-130 fuselage. The cutout is about 11" wide and 7" high.
Sampling inlets on port side of NSF C130. The upper inlet is a counterflow virtual impactor (CVI) used to sample cloud droplets. Two of the NCAR HIAPER Modular Inlets (HIMIL) are visible, one on the side of the fuselage and one on the belly.
