Urbanova is a consortium of university, city, public utility companies and other urban partners focused on the development of smart city technologies to promote community and individual well-being and health in an area located near central Spokane, WA, USA. This portion of the Spokane urban area exhibits a gradient of landuse types encompassing a modern university district, a growing commercial area, and low-to-medium income residential neighborhoods. This urban area is bisected by the I-90 freeway and a major railroad line along with a network of busy arterial and surface streets. In this paper, we describe the initial deployment of a network of smart sensors for air quality and related parameters and use results from this network to inform a high resolution urban modeling system: ENVI-Met. The initial sensors include measurements of CO2, PM2.5, temperature, humidity, and pressure using novel, inexpensive small sensors deployed in smart streetlights. In this paper, the urban computational fluid dynamics model, ENVI-Met is used with sensor data for PM2.5 to estimate roadway PM emissions. This is a first step toward an integrated, multi-scale measurement and modeling system for Urbanova including more than a dozen sensors, a research grade reference monitoring site, the AIRPACT air quality forecast system operating with 4 km and 1.3 km grid sizes, and high resolution WRF-Urban modeling.
