Air Quality

Rapidly Deployable PM Measurements We have been working with Shantanu Jathar’s group in the Department of Mechanical Engineering at Colorado State University to develop an easily deployable PM measurement system centered on the POPS optical particle counter. The system has a solar panel and battery system to enable 24-hour measurements of aerosol size distributions.

Spatial Mapping of Aerosol Size Distributions Using the solar-powered POPS system, the Jathar group will be carrying out a series of simultaneous size distribution measurements at multiple locations to examine aerosol transportation mechanics and evolution of particle size over different spatial scales.

Indoor Air Quality (HOMEChem) Handix Scientific loaned four of our POPS particle counters to the HOMEChem study, a large project examining chemistry of indoor environments. Prof. Delphine Farmer's group (Chemistry, Colorado State University) operated the instruments and deployed them in different rooms in a test house to examine particle transport patterns and timescales. This will help researchers understand how emissions in different areas of the home can affect occupants.
