The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Crown size and growing space requirement of common tree species in urban centres, parks, and forests (2015, background): “Nowak et al. (2013, 2014) and Dobbs et al. (2014) report about he effects of trees on air quality through air pollution removal.”
Nature Contact and Human Health: A Research Agenda (2017, background): “In urban settings, tree canopy may reduce ambient levels of particulate matter and gaseous air pollutants, although most studies find this air-quality improvement to be slight (Nowak et al. 2013; Nowak et al. 2014).”
Perception and preference of trees: A psychological contribution to tree species selection in urban areas (2016, background): “…et al., 2011), atmospheric carbon dioxide (CO2, Nowak and Dwyer, 2007; Escobedo et al., 2011), rainfall runoff, flooding, noise levels, and wind speed (Tyrväinen et al., 2005; Nowak and Dwyer, 2007), and remove air pollutants (Nowak and Dwyer, 2007; Escobedo et al., 2011; Nowak et al., 2014).”
Exploring pathways linking greenspace to health: Theoretical and methodological guidance (2017, background): “There is a general consensus that air pollutant concentrations are lower around greenspace (Nowak et al., 2014; Morani et al., 2011; Hirabayashi and Nowak, 2016; David Suzuki Foundation, 2015; Planting Healthy Air, 2016).”
