Recent evidence suggests that urban forms and materials can help to mediate temporal variation of microclimates and that landscape modifications can potentially reduce temperatures and increase accessibility to outdoor environments. To understand the relationship between urban form and temperature moderation, we examined the spatial and temporal variation of air temperature throughout one desert city—Doha, Qatar—by conducting vehicle traverses using highly resolved temperature and GPS data logs to determine spatial differences in summertime air temperatures. To help explain near-surface air temperatures using land cover variables, we employed three statistical approaches: Ordinary Least Squares (OLS), Regression Tree Analysis (RTA), and Random Forest …

The Portland-Vancouver Urban Long Term Research Area (ULTRA-Ex) is a multidisciplinary project aimed at understanding the feedbacks between human and natural systems in urban settings. The ULTRA-Ex project is seeking to answer the overarching question: How do human governance and biophysical systems respond interactively to both press and pulse disturbances in urban socio-ecological systems?

This presentation provides early observations and findings from the PV ULTRA-Ex project.
