International Workshop on Comparing Ice Nucleation Measuring Systems 2014 (ICIS 2014)

这一努力将支持美国研究人员参加一个研讨会，该研讨会将汇集一个国际大气科学家小组，他们是研究环境气溶胶颗粒与含冰云形成关系的专家。准确模拟气溶胶-云相互作用的能力是预测地球的最大不确定性之一。的气候。参与的美国科学家包括来自领先的冰测量小组的科学家。该项目的一个更广泛的影响是，它使美国科学家，包括他们的博士后研究员和研究生，能够获得一个特殊的最先进的室设施，进行空气污染，天气和气候的研究。AIDA室是独一无二的，因为它的尺寸，温度范围和全面的痕量气体，气溶胶和云仪器的组合。拟议的研讨会为美国科学家提供了一个机会，以评估他们的仪器与其他类似仪器的性能比较。研讨会将在大气中的气溶胶相互作用和动力学（AIDA）在卡尔斯鲁厄理工学院在德国，世界？这是在受控环境中制造冰云的最重要的设施。 来自大学、政府实验室和私人研究机构的云和气溶胶科学家将聚集在AIDA，目的是比较他们用于表征冰形成气溶胶的最先进仪器。科学家们将使用AIDA室在各种与大气相关的测试气溶胶上进行冰核化，包括矿物粉尘，生物气溶胶，金属氧化物和可溶性材料。将使用许多单独的质谱仪来确定气溶胶的大小和组成。将每台仪器的结果与其他仪器的结果进行比较。这项活动将提供宝贵的信息，以确定实验室和实地数据的相似性和差异是否归因于仪器性能或气溶胶变异性。

This effort will support US researchers to participate in a workshop that will bring together an international group of atmospheric scientists who are experts in conducting research on the relationship of ambient aerosol particles to the formation of ice-containing clouds. The ability to accurately model aerosol-cloud interactions is one of the largest uncertainties in predicting the Earth?s climate. Participating US scientists include those from leading ice measurement groups. One broader impact of this project is that it enables US scientists, including their postdoctoral fellows and graduate students, to have access to an exceptional state-of-the-art chamber facility for conducting research on air pollution, weather, and climate. The AIDA chamber is unique due to the combination of its size, temperature range, and comprehensive trace gas, aerosol, and cloud instrumentation. The proposed workshop offers US scientists an opportunity to evaluate the performance of their instruments in comparison with other similar instruments.The workshop will take place at the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) at the Karlsruhe Institute of Technology in Germany, the world?s foremost facility for producing ice clouds in a controlled setting. Cloud and aerosol scientists from universities, government laboratories, and private research institutes will gather at AIDA for the purpose of comparing their state-of-the-art instruments for characterizing ice-forming aerosol. The scientists will use the AIDA chamber to nucleate ice on a variety of test aerosols of atmospheric relevance including mineral dust, biological aerosol, metal oxides and soluble materials. A number of individual mass spectrometers will be used to determine aerosol size and composition. The results from each instrument will be compared with the results obtained by the others. This activity will provide valuable information for determining whether similarities and differences in laboratory and field data are attributable to instrument performance or to aerosol variability.
