Title: Validation of ice formation in cloud resolving models via remote sensing

Abstract:
Ice formation in mixed phase stratocumulus clouds is poorly understood. 
Cloud resolving model simulations including the commonly assumed 
processes for ice formation and multiplication generally cannot 
reproduce the measurements. In this talk I will show how possible new 
candidates for ice formation can be validated using model simulations 
and remote sensing measurements. I will focus on lidar and radar 
measurements of a particular cloud deck observed in the MPACE campaign 
on the Northern coast of Alaska. From the results of cloud resolving 
model calculations including several different ice formation processes, 
the lidar and radar measurements were simulated and compared to the real 
measurements. This allows to rule out some of the ice formation candidates.
