Detailed Summary

Project Dates: 2014 - Present

The Boulder ozone project began in the summer of 2015 by the Hannigan group. The project had two main goals: 1) To demonstrate the ability of low-cost electrochemical sensors to detect variability in ozone concentrations and 2) To examine the variability of ground level ozone in a small spatial scale (< 1 km^2). U-Pods were deployed at both the CU campus (urban setting) and the South Boulder Creek ozone monitoring station (rural setting) in order to measure the differences between urban and rural ozone levels.

In June of 2015, Kira Sadighi and Lauren Deanes deployed pods at the BAO Tower in Erie and the South Boulder Creek (SBC) ozone monitoring sites in order to co-locate them and generate data for a calibration. Then the pods were deployed from late June to early July of 2015 on the CU campus (at 3 locations) and near the SBC monitoring site (at 4 locations). The pod locations varied in regards to distance to roadway and distance to vegetation.

Their findings were presented at the 2015 ISES (International Society of Exposure Science) conference in Henderson, NV. 

The data collected during the summer of 2015 is being processed further during the summer and fall of 2016 by Lucy Cheadle and Kira Sadighi. They are working to analyze the results for more complicated trends and publish their findings.
