In collaboration with the Central Arizona Phoenix Long Term Ecological Research observatory (CAP-LTER) and the UREx Sustainability Research Network led by Arizona State University, we are conducting field work and modeling science to understand the impact of urban climate on infrastructure, water and energy use, and human health, especially at the “human scale” of 1-10 meters where people live and make most of their important decisions. Our urban flux tower and microclimate observations are available for several years at fine urban scales via CAP-LTER. A new method for mobile platform microclimate and air quality data processing and visualization has been developed and is being published in a new software package, TraVIS, in partnership with the Technische Universitat Kaiserslautern. This mobile sensor platform capability is relevant for canopy ecology, microclimate, air quality, and precision agriculture applications. Modeling is underway to develop an improved understanding of systems-level reliability, resilience, and efficiency of urban water and energy systems in Phoenix and Arizona. Funding is provided by the National Science Foundation, local utilities like the Salt River Project, and private partners (EF-1049251, BCS-1026865, EAR-1360509, ENG-1509077, GEO-0816168, BCS-1444755).
