U.S.-Sweden Cooperative Research: In-Situ Measurement of Aerosol Particles

该奖项将支持伊利诺伊大学厄巴纳-香槟分校的Mark Rood博士和瑞典隆德理工学院的Hans Christen Hansson博士之间的合作研究。这一拟议研究项目的主要目标是开发一种仪器，可以在现场条件下同时测量气溶胶粒子的吸湿、化学和热特性，并具有较短的响应时间。有关气溶胶颗粒的吸湿性、组成和热挥发度的信息将由该仪器获得，作为颗粒大小的函数。鲁德教授和汉森教授将利用他们个人的专业知识来开发仪器的部件，然后他们将把各个部件集成在一起，组装成一个完整的气溶胶采样系统。目前还没有一种仪器可以同时研究气溶胶的吸湿和热性质作为颗粒大小的函数。该仪器可用于大气化学、大气物理、大气污染控制技术等相关实验。

This award will support collaborative research between Dr. Mark Rood, University of Illinois at Urbana-Champaign and Dr. Hans Christen Hansson, Lund Institute of Technology, Sweden. The primary objective for this proposed research project is to develop an instrument that can be used to measure simultaneously the hygroscopic, chemical, and thermal characteristics of aerosol particles under in-situ conditions and with a short time response. Information about the aerosol particles hygroscopicity, composition, and thermal volatility will be obtained by this instrument as a function of particle size. Professors Rood and Hansson will utilize their individual expertise to develop components of the instrument and then they will integrate the individual components to assemble a complete aerosol sampling system. No instrument exists that can simultaneously study the hygroscopic and thermal properties of an aerosol as a function of particle size. Such instrument can be used to perform atmospheric chemistry, atmospheric physics, and air pollution control technology related experiments.
