Acquisition of a Global Sizing Velocimeter, Aerodynamic Particle Sizer, and Tethersonde Array to Advance Aerosol Technology Engineering and Science on the High Plains

德奥特西德克萨斯农工大学(WTAMU)是一所地区性大学，是一所新兴的研究机构，旨在通过购买空气动力学颗粒测定仪(APS)、全球测速测速仪(GSV)、振动孔板气溶胶发生器(VOAG)和系绳探测仪来加强农业空气质量计划，该仪器配备了在农业作业附近测量边界层参数的设备。获得所需仪器的目的是将先进的工程技术和原则应用于解决与生产农业有关的环境问题。目标包括了解大气边界层以实现更好的扩散建模，准确测量抑尘效果，并将现代工程仪器整合到高中和本科课堂、实验室，以及正在进行的美国国家科学基金会STEP和S-STEM计划中的研究经验。研究人员将与两个机构结盟，一个学术机构和一个研究机构，代表包括机械工程、农业和生物工程以及环境科学在内的几个学科，将使用所要求的设备为解决与农业和环境质量的几个方面相关的问题提供数据。GSV和系留探测仪都将用于深入了解集中饲养动物作业(CAFO)周围的边界层发展，这对于包括芳香化合物和PM在内的污染物的真实扩散建模是必要的，这两种污染物都越来越受到美国环保局的审查。GSV和APS可以收集必要的数据，以便对CAFO的尘埃抑制进行关键评估，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.
