NO2 concentrations were measured during driving, walking and cycling commutes using Earthsense zephyrs. Four routes were taken. Measruements were averaged by trip and ratios of NO2 in car to active commute (i.e NO2 car/ NO2 walking or NO2 car/ NO2 cycle) were calculated for each trip and route.

O3 concentrations were measured during driving, walking and cycling commutes using Earthsense zephyrs. Four routes were taken. Measruements were averaged by trip and ratios of O3 in car to active commute (i.e O3 car/ O3 walking or O3 car/ O3 cycle) were calculated for each trip and route.

PM2.5 concentrations were measured during driving, walking and cycling commutes using Earthsense zephyrs. Four routes were taken. Measruements were averaged by trip and ratios of PM2.5 in car to active commute (i.e PM2.5 car/ PM2.5 walking or PM2.5 car/ PM2.5 cycle) were calculated for each trip and route.

Using EathSense Zephyrs, the concentrations of NO2, O3 and PM2.5 was measured on morning commutes across 4 routes in Leicester. Using the concentrations of each pollutant measured on the routes, average journey times and previous measurements of commuter inhalation rates, the inhaled dose of each pollutant was estimated on each route.

Using EathSense Zephyrs, the concentrations of NO2, O3 and PM2.5 was measured on morning commutes accros 4 routes in Leicester. The data file Commuter pollutant concentrations by route min averaged.csv shows meadured concentrations of these pollutants along the commutes for people either walking, driving or cycling, averaged to 1- minute time resolution (Commuter pollutant concentrations by route min averaged.csv).

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.
