Interpretation of organic components from positive matrix factorization of aerosol mass spectrometric data
The organic aerosol (OA) dataset from an Aerodyne Aerosol Mass Spectrometer (Q-AMS) collected at the Pittsburgh Air Quality Study (PAQS) in September 2002 was analyzed with Positive Matrix Factorization (PMF). Three components – hydrocarbon-like organic aerosol OA (HOA), a highly-oxygenated OA (OOA-1) that correlates well with sulfate, and a less-oxygenated, semi-volatile OA (OOA-2) that correl...

This manuscript contains an extensive analysis of what happens when Q-mode Aerosol Mass Spectrometer (Q-AMS) data are analyzed by the PMF model, using the program PMF2. The authors have attempted to find limits of what may be reliably deduced about the sources of organic aerosol in such analysis. As a result of their work, they express caveats against interpreting the results too strongly. This...

My first review submission has caused misunderstandings. (1) I wrote that a second review is needed. This means the following: when a number of changes are requested in a manuscript, then the editors often wish to know if the reviewer(s) wish to see the final manuscript before it is accepted for publication. In this case, I request a number of changes. My remark about the second review means th...

As mentioned along with my first comments, this manuscript represents an important contribution to the puzzle how organic Q-AMS spectral data can be related to OA sources and secondary OA components. I have a few general and some more specific comments with a focus on the real data case. General comments: A) Verification of factor interpretations Abstract, p. 6731, lines 4-5: “It is critical to...

We thank referee P. Paatero for his detailed review and thoughtful comments on this work, which we think have helped us improve the work significantly. We’ve repeated his comments here in italics, numbering the items for easy cross-reference. Our replies follow each excerpt. Our response to these comments has been divided into two parts to fit within the allowed page length for Author Comments ...
