concentrations and is packaged in a convenient, battery-powered module for easy use in the field. The stainless steel diffusion dryers can be filled with various media to dry or otherwise condition sampled air streams. The Continuous Flow Diffusion Chamber, originally developed by Colorado State University, provides continuous measurements of ice nucleating particles at conditions relevant to mixed phase clouds. It is capable of quasi-autonomous and semi-continuous measurements from the ground with sufficient sensitivity to measure atmospherically relevant ice nucleating particle (INP) concentrations (~ 1 L-1).
