Development of the Multi-Angle Snowflake Camera for Improved HydrometeorHabit- Diameter-Mass-Fallspeed Parameterizations

摘要

We neared completion of a new instrument for measurements of habit- diameter-mass-fallspeed relationships for hydrometeors. Such relationships are essential for accurate radar retrievals and numerical simulations of storms. Completion of the Multi-angle Snowflake Camera (MASC) will provide for the first time automated measurement of these properties. The instrument is currently at a stage suitable for lab-bench tests. Further support is needed to cover completion of an outdoor version of the probe, software development and scientific analysis of results obtained in high-desert mountainous terrain.
