Project Description/Abstract

Mini-DOAS (miniaturized-differential optical atmospheric spectrometer) is a portable, small, inexpensive instrument. This proposal is for the funding needed to purchase the component parts with which to construct such an instrument. The instrument will be used to study the stack emissions of point source emitters in the local area. These point sources emit gases that are the major low-level atmospheric gas pollutants. SO2, NO2, O3 and components of acid rain. The instrument will be used to monitor those emissions and will serve as an independent source of stack gas emission data with which to compare to the self-reported (to the Massachusetts Department of Environmental Protection) record of emissions. Other smaller plants exempt from reporting requirements will also be monitored. The instrument will also be available to students in undergraduate research and will be available for other faculty to use in astronomy, volcanology and meteorology.
