Near-Road NO2 Monitors
PI: Timothy Larson (UW)
Dates: 06/16/2012 – 06/15/2013
Final Project Report: PacTrans-20-UW-Larson
Near-road monitoring of nitrogen dioxide (NO2) in major urban areas in the U.S. will be required by 2013. It is not yet known exactly how many urban areas will be in attainment of the new NO2 air quality standard, due to a lack of historical near-road monitoring information. The answer is sensitive to the exact siting of these monitors with respect to the roadway and EPA’s siting guidance for near-road NO2 monitors is not yet officially established.
