The overall goal of this joint project renewal proposal is to develop and characterise 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 characterisation 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 millimetre 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.

该联合项目更新建议的总体目标是开发和表征四种最近设计的光学方法，用于确定冰云元素的微物理和光学特性，并通过新的研究飞机光环进行原位测量。这四种仪器是来自Karlsruhe技术研究所的PHIP（粒子习惯成像和极性散射）和SID-3（小冰探测器MK 3）探针以及CIP（云成像探针）和大学和Mainz的Max-Planck Institute的CIP（云成像探针）和Max-Planck-Institute。飞机批准的SID-3和CIP仪器已在飞机上运送和部署，在第一个赠款期的36个月内，在飞机上，内部的云模拟室内AIDA。内部开发的仪器PHIP和Haloholo是在第一个资金期间开发和建造的。经过一些修改后，它们将在续签期的第一年内准备好飞机。原型仪器已经在基于地面的自由大气测量和云模拟室内AIDA中使用。使用这组仪器，可以获得冰云颗粒的全面表征，包括尺寸，外部和内部形态，表面粗糙度以及冰晶的角光散射特性，从一微米延伸到一毫米及以上。为了实现这一目标并将工具部署在2011年和2012年的Halo示范任务ML-CIRRRU，POLSTRACC和ACRIDICON中，至关重要的是：（1）开发全自动控制系统和数据采集软件。 （2）在真实气氛条件下测试这些仪器。 （3）开发自动图像数据分析工具，以从仪器数据集中提取微物理粒子参数。 （4）编译PHIP和Haloholo的认证文件，并进行飞行安全认证。 可以通过在云模拟室Aida的专门测试活动来实现任务（2）和（3）。 （3）固有的开发任务需要重大努力，因为它是SID-3，PHIPS和Haloholo最终仪器可交付成果的关键。
