The UCSD campus was used as a case study for several reasons.
There are various on-going construction projects and hence elevated
PM levels could be studied. Also, UCSD has established a unique
network of stations to monitor environmental conditions on campus
for the Decision Making using Real time Observations for Environmental
Systems (DEMROES) project (Dominguez et al., 2007) that
provided the microclimatic information and measurement infrastructure
necessary for this work. Furthermore, as the campus is
reminiscent of suburban environments, perceptions are not subject
to the urban versus rural dichotomy that could lead to location being
the parameter controlling perception, rather than air quality levels
themselves
