Abstract

The workshop on in situ airborne instrumentation: addressing and solving measurement problems in ice clouds, June 25-27, 2010, Oregon, aimed to identify unresolved questions concerning ice formation and evolution in ice clouds, assess the current state of instrumentation that can address these problems, introduce emerging technology that may overcome current measurement issues, and recommend future courses of action to improve our understanding of ice cloud microphysical. Eleven presentations were made covering measurement challenges associated measuring the composition and concentration of all the modes of ice nuclei (IN), measuring the morphology, mass, surface, and optical properties of individual ice crystals over all sizes, and measuring temperature, humidity, and winds in clouds accurately. It was found that cloud lifetimes are sensitive to the sedimentation velocity of the ice crystals, as are the rates of aggregation and riming that depend on the relative fall velocities of ice crystals and supercooled water droplets.
