2.2. Equipment and sampling
Atmospheric nanoparticles were measured using a NanoScan
Scanning Mobility Particle Sizer model 3910 (TSI Inc.), every 60 s
with a 0.75 L min–1 inlet flow and a 0.25 L min–1 CPC flow. This
equipment uses isopropyl alcohol as condensation liquid, and
considers particles between 10 and 420 nm distributed across 13
channels. Meteorological variables such as air temperature (°C),
relative humidity (%), wind direction (°), wind speed (m s–1), and
solar radiation (kJ m–2) were continuously measured through a
weather station.
