چکیده
This is a very interesting paper looking at combining HNMR and AMS data to deliver a more complete picture of organic particulates in a polluted European environment. The real novelty of this work is in the combination of the independent factorisation of both datasets to deliver insights into the processes that might not be possible with only one of the datasets. The two data sources do not agree completely, however rather than try to establish which technique is ‘right’, the paper wisely focuses on chemical reasons for these discrepancies in an attempt to better elucidate the processes being observed.

Authors Reply. Accepted. We reworded the sentence into the following: PMF is becoming common for organic source apportionment (Zhang et al., 2005; Lanz et al., 2007) and factor analysis of AMS data using PMF in its diverse implementations (including e.g. ME-2) has extracted biomass burning organic aerosol (BBOA) factors in multiple sites (Aiken et al., 2010; Elsasser et al., 2012; Crippa et al....

these results are not shown graphically, which would be very useful to see. These could very easily be included as supplementary material. Additionally, the factorisation also presumably needed to employ an estimate of measurement precision but the authors give no explanation for how this data was generated. The fact the Q/Qexp values in figure 5 are very high (around 30) may suggest that these...

Characterization of urban aerosol using aerosol mass spectrometry and proton nuclear magnetic resonance spectroscopy
Particulate matter was measured during August and September of 2006 in Houston as part of the Texas Air Quality Study II Radical and Aerosol Measurement Project. Aerosol size and composition were determined using an Aerodyne quadrupole aerosol mass spectrometer. Aerosol was dominated by sulfate (4.1 2.6 mg m 3) and organic material (5.5 4.0 mg m 3), with contributions of organic material from b...
