Description: Das Projekt "Airborne in-situ characterisation of the microphysical and optical properties of small ice crystals and large hydrometeors (AMOSIL): HALO implementation and analysis methodology" wird vom Umweltbundesamt gefördert und von Johannes Gutenberg-Universität Mainz, Institut für Physik der Atmosphäre durchgeführt. The overall goal of this joint project renewal proposal is to develop and characterize four recently devised optical methods for the determination of the microphysical and optical properties of ice cloud elements and make them available for in situ measurements with the new research aircraft HALO. The four instruments are the PHIPS (Particle Habit Imaging and Polar Scattering) and the SID-3 (Small Ice Detector Mk 3) probes from Karlsruhe Institute of Technology as well as the CIP (Cloud Imaging Probe) and the holographic instrument HALOHOLO from the University and the Max-Planck-Institute for Chemistry in Mainz. The aircraft approved instruments SID-3 and CIP have been delivered and deployed on aircraft, and inside the cloud simulation chamber AIDA of KIT within the 36 month of the first grant period. The in-house developed instruments PHIPS and HALOHOLO have been developed and built during the first funding period. After some modifications they will be aircraft ready within the first year of the renewal period. The prototype instruments have already been used during ground based free atmospheric measurements and inside the cloud simulation chamber AIDA. With this set of instruments a comprehensive characterization of ice cloud particles can be obtained including the size, the external and internal morphology, the surface roughness, and the angular light scattering properties of ice crystals over a broad size range extending from one micron to one millimeter and above. To reach this goal and deploy the instruments in the HALO demonstration missions ML-CIRRUS, POLSTRACC, and ACRIDICON in 2011 and 2012 it is essential to: (1) Develop fully automated control systems and data acquisition software. (2) Test these instruments under real atmosphere conditions. (3) Develop automated image data analysis tools that extract microphysical particle parameters from the instrument data sets. (4) Compile the certification documentation for PHIPS and HALOHOLO and conduct the flight safety certification. The tasks (2) and (3) can be achieved through dedicated test campaigns at the cloud simulation chamber AIDA. The development task inherent in (3) requires major efforts as it is the key to the final instrument deliverables of SID-3, PHIPS and HALOHOLO.
