Abstract
This work provides interesting insights into urban emissions and their contribution to the BC loading in Helsinki, at two sites influenced by contrasting combustion sources. They apportioned BC sources by using and comparing two methods: (1) the model of Sandradewi et al (2008) based on multiwavelength aethalometer measurements and (2) the PMF applied to organic and refractory black carbon components measured by a SPAMS. The methodology regarding the SP-AMS and coating estimation would benefit from some elaboration.
