Mobile Air Quality Monitoring on UNT Campus

On campus air quality surveys:

Mobile monitoring campaigns were carried out by bicyclists surrounding a university campus using a low-cost particle sensor and a GPS data logger. Geotagged 1-minute PM_2.5 measurements were collected along a fixed route at fixed time schedule.

Spatio-temporal pattern visualization:

Spatial-temporal patterns of PM_2.5 concentrations are quantified and the significance levels of within-day and inter-day differences are tested.

Identifying driving landscape factors:

The factors influencing PM_2.5 dynamics will be identified, including meteorological factors, traffic, landscape horizontal compositions (e.g., the proportion of green spaces, building footprints) and vertical structure (e.g., average building and tree height) that are derived from earth observation data.
