The Urban Resiliency programs are:

Operation Healthy Air (April 2017–present)

Our newest program, Operation Healthy Air will engage partners and participants to map and measure how differences in their environment—such as amount of trees or pavement, affect local air quality and temperature. Starting with pilot sampling “campaigns” in Long Beach, and Chino, and the Inland Empire (e.g. Riverside and Redlands) in the summer of 2017, we will look to expand in 2018 to greater Los Angeles and other cities. Find out more on how to get involved.

Operation Resilient Trees (July 2015–June 2017)

During Resilient Trees 1.0 (July 2015–May 2016), citizen scientists collected measurements on 10 different tree species across a 150 mile-long geographical gradient in order to better understand each species’ water use, cooling benefit, and physiological performance in each climate zone. Resilient Trees 2.0 (July-December 2016) continued this work with almost 400 tree measurements on a new set of 10 species. Resilient Trees 3.0 (January–June 2017) will focus on another set of 10 species, culminating in valuable research on 30 species of urban trees that are potentially “climate-ready.”

Operation Tree Canopy (August 2014–2015)

Citizen scientists collected on-the-ground data to corroborate NASA aerial imagery of the study region. Recording tree species, health, size, and taking a physical sample of each tree’s leaves, citizen scientists provided essential ground-truthing for the climate, land cover, and temperature models being developed from NASA’s data. The data are currently being analyzed and we expect a publication in late 2017.
