Convective clouds may cause serious economic damage due to gusty winds, heavy showers and precipitation which partly may include hail or graupel and thunderstorms. The dynamics and vigor of these distinct weather events are determined by microphysical processes in the course of the cloud and precipitation formation which can be modified by aerosol particles and interactions with atmospheric radiation. Furthermore, convective clouds profoundly process and redistribute trace gases and aerosol particles due to vertical transport and entrainment or detrainment. To study these interactions between trace gases, aerosol particles, the cloud and precipitation formation, and atmospheric radiation in extra-tropical convective clouds the HALO demo mission “Aerosol, Cloud, Precipitation, and Radiation Interactions and Dynamics of Extra-Tropical Convective Cloud Systems (ACRIDICON)” was proposed. ACRIDICON contributes to two foci of the SPP 1294: “Clouds and Precipitation” and “Transport and Dynamics in the Troposphere and Lower Stratosphere”. The present proposal is mainly to organize and manage ACRIDICON and to partly contribute to the data analysis and evaluation of radiation measurements collected during this HALO demo mission.

对流云可能会造成严重的经济损失，因为阵风，大雨和降水，其中部分可能包括冰雹或霰和雷暴。这些不同的天气事件的动态和活力是由云和降水形成过程中的微物理过程决定的，而云和降水的形成过程可以被气溶胶粒子和与大气辐射的相互作用所改变。此外，对流云深刻的过程和再分配微量气体和气溶胶粒子由于垂直输送和夹带或消散。为了研究热带外对流云中痕量气体、气溶胶粒子、云和降水的形成以及大气辐射之间的这些相互作用，提出了HALO演示使命“热带外对流云系统的气溶胶、云、降水和辐射相互作用和动力学”。ACRIDICON为SPP 1294的两个焦点做出了贡献：“云和降水”和“对流层和平流层下部的传输和动力学”。目前的建议主要是组织和管理ACRIDICON，并对数据分析和评价在这次HALO演示使命期间收集的辐射测量作出部分贡献。
