Non-parametric Trajectory Analysis of High Time Resolution PM2.5 Data from EPA’s Near-Road Monitoring Network Sites

Analysis of high time resolution (1 min., 5 min.) PM2.5 concentration data from EPA's Near Road Monitoring Network sites located in St. Louis, Denver and Cincinnati using Non-parametric Trajectory Analysis (NTA) to quantify impact of roadway on measured levels.

Impact/Purpose

Improve understanding of impact of major roadways on PM2.5 concentrations at EPA's Near Road Monitoring Network sites.
