Abstract ATM-9501112 Kritz, Mark A. State University of New York at Albany Title: Development of a Sampling Strategy for the Verification of Global Transport Models Using Airborne Radon Measurement Although the verification of global transport models using airborne radon measurementq has received attention at two major workshops, the observations available thus far for intercomparsion with model predictions are fragmentary and were not always obtained using a sampling strategy designed with such intercomparsions in mind. In this project we will work closely with two prominent global modeling groups on the development of such a strategy, with emphasis on designing a measurement program which will permit the evaluation of competing computational schemes for parameterizing vertical convective transport in 3-D models. In this effort the global circulation and assimilation wind models under development at the Global Climate Dynamics Program at NCAR and at the Data Assimilation Office at the NASA Goddard Space Flight Center will be used to stimulate free tropospheric radon distributions over North America using a variety of convective parameterizations. Working with researchers in these organizations, the PI will examine these distributions and simulate the radon concentrations which would be encountered and sampled by instrumentation on an aircraft following various flight paths through such distributions in order to develop flight plans and sampling strategies which would allow an efficient evaluation of model performance. In this effort the PI will also use the radon vertical profiles acquired by his group in the summer of 1994. (The 1994 data set will also be made available to the modeling community on the internet.) This research is important because it attempts to develop an observational basis for testing and improving the way GCMs simulation vertical transports.

Am-9501112 Kritz，Mark A.纽约州立大学奥尔巴尼分校标题：利用机载测氡验证全球传输模型的抽样策略的发展尽管使用机载测氡对全球传输模型的验证在两个主要研讨会上受到了关注，但迄今为止可用于与模型预测进行比较的观测是零散的，并不总是使用考虑到这种相互比较而设计的采样策略来获得的。在这个项目中，我们将与两个著名的全球模拟小组密切合作，制定这样的战略，重点是设计一个测量计划，允许评估相互竞争的计算方案，以便在3-D模式中对垂直对流输送进行参数化。在这项工作中，美国国家航空航天局全球气候动力学方案和美国宇航局戈达德空间飞行中心数据同化办公室正在开发的全球环流和同化风模型将被用来利用各种对流参数来模拟北美上空的自由对流层氡分布。PI将与这些组织的研究人员合作，检查这些分布，并通过仪器在飞机上按照不同的飞行路线通过这些分布来模拟遇到和采样的氡浓度，以便制定飞行计划和采样策略，从而能够有效地评估模型的性能。在这项工作中，国际和平研究所还将使用他的小组在1994年夏天获得的氡垂直剖面。(1994年的数据集也将在因特网上提供给模型界。)这项研究很重要，因为它试图为测试和改进GCMS模拟垂直运输的方式发展一个观测基础。
