0923250 DeOtteWest Texas A M University（WTAMU）是一所新兴的研究机构，旨在通过收购空气动力学颗粒粒度仪（APS）、全球粒度测速仪（GSV）、振动孔板气溶胶发生器（VOAG）和系留探空仪来加强农业空气质量计划，这些设备用于测量农业作业附近的边界层参数。获得所需仪器的目的是应用先进的工程技术和原理来解决与生产农业相关的环境问题。目标包括了解大气边界层，以便更好地进行扩散建模，精确测量抑尘效果，并将现代工程仪器集成到高中和本科教室，实验室和研究经验中，并与正在进行的NSF STEP和S-STEM计划相结合。代表包括机械工程、农业和生物工程以及环境科学在内的多个学科的联合国环境规划署将利用所要求的设备提供数据，以解决与农业和环境质量的几个方面有关的问题。GSV和系留探空仪都将被应用于提供深入了解周围的边界层发展集中的动物饲养业务（CAFO）所需的污染物，包括芳香族化合物和PM，这两者都越来越受到美国环保局审查的现实分散建模。GSV和APS可以收集必要的数据来严格评估CAFO的抑尘效果，因此可以将合理的工程原理应用于这一重要问题。

0923250DeOtteWest Texas A&M University (WTAMU) is a regional university emerging as a research institution and seeks to strengthen the agricultural air quality program through acquisition of an aerodynamic particle sizer (APS), global sizing velocimeter (GSV), vibrating orifice aerosol generator (VOAG), and tethersonde equipped to measure parameters of the boundary layer in the vicinity of agricultural operations. The goal of acquiring the requested instrumentation is to apply advanced engineering techniques and principles to the solution of environmental problems associated with production agriculture. Objectives include understanding atmospheric boundary layers to allow better dispersion modeling, accurate measurement of the efficacy of dust suppression, and integration of modern engineering instrumentation into high school and undergraduate classrooms, labs, and research experiences in conjunction with ongoing NSF STEP and S-STEM programs.Investigators aligned with two agencies, one academic and one research oriented, and representing several disciplines including mechanical engineering, agricultural and biological engineering, and environmental science, will use the requested equipment to provide data for the solution of problems associated with several aspects of agriculture and environmental quality. The GSV and tethersonde will all be applied to provide the insight into boundary layer development around concentrated animal feeding operations (CAFOs) necessary for realistic dispersion modeling of pollutants including aromatic compounds and PM, both of which are increasingly being scrutinized by the USEPA. The GSV and APS can gather data necessary to critically evaluate dust suppression at CAFOs so sound engineering principles may be applied to this important problem.
