Outdoor air quality and microclimate conditions directly affect the environments that buildings and cities are responsible for managing. Construction sites generate particulate and gaseous emissions that are subject to regulatory thresholds. Urban development patterns create heat islands and air quality gradients that affect public health and infrastructure planning. Weather and environmental data, where it exists at all, is often aggregated at a scale too coarse to inform site-level decisions.

FLO2 extends the same sensing and data infrastructure used inside buildings to the external environment, across four distinct application areas.
