Abstract. A new inlet for studying the aerosol particles and hydrometeor residuals that compose mixed-phase clouds – the phaSe seParation Inlet for Droplets icE residuals and inteRstitial aerosol particles (SPIDER) – is described here. SPIDER combines a Large-Pumped Counterflow Virtual Impactor (L-PCVI), a flow tube evaporation chamber, and a Pumped Counterflow Virtual Impactor (PCVI) to separate droplets, ice crystals, and interstitial aerosol particles for simultaneous sampling. Laboratory verification tests of each individual component and then the composite SPIDER system were conducted. SPIDER was then deployed at Storm Peak Laboratory (SPL), a mountain-top research facility at 3210 m a.s.l. in the Rocky Mountains. SPIDER performance as a field instrument is presented with data that demonstrates its capability of separating cloud elements and interstitial aerosol particle. Possible design improvements of SPIDER are also suggested.

Short summary
A new inlet for studying the small particles, droplets and ice crystals that compose mixed-phase clouds has been constructed and is described here. This new inlet was then deployed at Storm Peak Laboratory, a mountain-top research facility in Colorado and within the Rocky Mountains. We present the performance of the new inlet to demonstrates its capability of separating ice, droplets and small particles.
