Concentrations of NO2, O3 and PM2.5 were measured during morning driving, walking or cycling commutes. These measurements were made using EarthSense zephyrs.
The data file shows the concentrations of each pollutant measured along 4 different routes, averaged per trip. Along with these commuting measruements, metorological data was downloaded from the University of Leicester AURN AQ monitoring station and merged into the same file.
