Air quality varies significantly between the two sites. CS is clearly
more burdened from an environmental point of view, as the PM count
distribution has a long tail towards higher values (Fig. 3a,b). The
minimum values are fairly similar for both sites (around 53 part/l),
but the maximum value is 3 times higher at CS (2868 part/l as
opposed to 967 part/l, or 80.3 μg m−3 as opposed to 27.1 μg m−3
). The
mean value is 4 times higher (806 part/l as opposed to 216 part/l, or
22.6 μg m−3 as opposed to 6.1 μg m−3
). The measurements reflect
the higher pollution load of the CS, which we attribute mainly to
dust loading. However, given that the campus is an open area and
well ventilated in an otherwise clean region, the absolute values are
considered rather good
