Observations at both sites show similar trends; yet with differences that still need to be explored. Strong diurnal variations at Pinerole transitions between boundary layer and free troposphere Dust events show higher concentrations in free troposphere (esp. 1 um) Transport of black carbon from Europe and biomass burning concentrations higher in boundary layer Monte Pinerole PACMEx Site Data Collection Timeline at Pinerole
