A newly acquired aerosol mass spectrometer (AMS) will be deployed at the PROPHET (Program for Research on Oxidants: Photochemistry, Emissions, and Transport) site in Northern Michigan during the summer of 2001. The PI will attempt to measure deposition fluxes of individual species associated with aerosol particles. The size-segregated ambient aerosol composition will be measured at a fast rate, including the ions sulfate, nitrate, and ammonium. Fluxes will be determined using the eddy correlation method. This project is supported as a Small Grant for Exploratory Research (SGER) and is a collaboration with Aerodyne Research Inc., the manufacturers of the AMS instruments.

一台新获得的气溶胶质谱仪（AMS）将于2001年夏天部署在密歇根州北部的PROPHET（氧化剂研究计划：光化学、排放和运输）站点。PI将尝试测量与气溶胶颗粒有关的单个物种的沉积通量。将以快速速率测量大小分离的环境气溶胶成分，包括硫酸盐离子、硝酸盐离子和铵离子。通量将使用涡流相关法确定。该项目得到了探索性研究（SGER）小额拨款的支持，并与AMS仪器制造商Aerodyne研究公司合作。
