项目摘要
9523731 Hopke The PIs have developed and tested a number of different mathematical techniques that can help extract information on source/receptor relationships in the atmospheric transport of airborne particulate matter from compositional data sets. These methods include techniques for projecting high dimensionality, multielemental composition data into two or three dimensions; and the integration of meteorological information in the form of back trajectory calculations into the analysis by creating a conditional probability field. For the interpretation of multivariate air quality data, the use of Neural Networks has been explored, as well as its combination with the minimal spanning tree technique. In this project, the development, testing, and application of new multivariate statistical methods to atmospheric sample composition data, primarily particles and precipitation, will be continued. Extensive collaborations have been established with atmospheric scientists from all parts of the world who have initiated field studies, including measurements in the Great Lake area, upstate New York, the Chesapeake Bay, as well as Australia, Finland and Sweden. The PI's analysis methods will provide new tools for examining data, and help extract maximum useful information from these data bases. Among the development and testing projects that will be continued are Positive Matrix Factorization, and multimodal factor analysis for looking at several different types of 3-way data tables.
PIs已经开发并测试了许多不同的数学技术,这些技术可以帮助从成分数据集中提取空气中颗粒物的大气输送中源/受体关系的信息。这些方法包括将高维、多元素成分数据投影到二维或三维的技术;并通过建立条件概率场,将气象信息以反轨迹计算的形式整合到分析中。对于多元空气质量数据的解释,已经探索了神经网络的使用,以及它与最小生成树技术的结合。在这个项目中,将继续开发、测试和应用新的多变量统计方法来处理大气样品成分数据,主要是颗粒和降水。已经与世界各地的大气科学家建立了广泛的合作关系,他们已经开始进行实地研究,包括在大湖地区、纽约州北部、切萨皮克湾以及澳大利亚、芬兰和瑞典进行测量。PI的分析方法将为检查数据提供新的工具,并帮助从这些数据库中提取最大有用的信息。将继续进行的开发和测试项目包括Positive Matrix Factorization,以及用于查看几种不同类型的3-way数据表的多模态因子分析。
