The authors have properly addressed the comments of the three referees and made substantial modifications to their manuscript.
However, the revised manuscript contains several obscurities and errors, so that substantial additional revision is needed.

Main text:
Many acronyms are not defined (written full-out) and some are defined too late. This is the case for GFF, DCM, GC-MS, EI, LOQ, the indices p and g of c, OM, fa, fw, Cbulk, POC, DOC, SM, Fem, ISS, OC/EC, and a.e.d. Acronyms should be defined when first used.
Lines 62-65: This paragraph should be rephrased.
Line 103: Why do the authors talk of “The first portion“? What was done with the other portion(s)?
Line 123: Replace “detectedin” by “detected in”.
Line 131: Replace “The identical samplers” by “Identical samplers”.
Line 145: It is unclear what is meant by “passive air samples”. Are they identical to the “field blanks”?
Line 172: It is unclear what the difference is between “cp” and“cTSP”, if any.
Line 179: How can the unit for the aerosol particle surface S be “cm-1”?
Line 181: Replace “uses only” by “use only”.
Line 182: It is unclear what is meant by “the fraction of OM”. Fraction in what? In the PM?
Line 195: Replace “concentration:” by “ concentration (Cbulk):”.
Line 199: “Karickhoff et al., 1981” is not in the Reference list. There is “Karickhoff, 1981” in that list, to which no reference is made within the text.
Line 277: Fig. S5 does not exist. Replace “S5” by “S4 ”.
Lines 287-288: The parentheses are unpaired.
Line 300: Replace “PAH compared” by “PAHs compared”.
Lines 303 and 305, Tables 2a and 2b: Replace “Castro Jimenéz 2012” by “ Castro Jimenéz et al., 2012”. Besides, it is unclear whether the reference “Tsapakis & Stephanou, 2005” is to “a” or “b” or perhaps both.
Line 313: Replace “along track” by “along the cruise track”.
Line 321: There is text missing here.
Line 325: Replace “Cabuk” by “Çabuk”.
Line 334: The term “a.e.d.” (presumably “aerodynamic equivalent diameter”) is a pleonasm. An “aerodynamic diameter” is implicitly “equivalent”. The correct term is “aerodynamic diameter (AD)”.
Lines 357-361, further in the main text, and also in the Supplementary Material: Figure captions should be below figures instead of above.
Line 364: Fig. 1b is much too small, so that one cannot judge whether is is properly discussed.
Line 438: See comment above with regard to the term “a.e.d.”.
Line 469: Replace “Nikolas” by “Nikolaos”.
Lines 477-482: The reference to “Albert et al., 2012” should come after that to “Akyüz et al., 2010”.
Lines 611-614: The reference to “Rowe et al., 2009” should come after that to “Ramdahl, 1983”.

Supplementary Material:
There are many acronyms that are not defined (written full-out). They should be defined or, as an alternative, for those acronyms that were defined in the main text, a general statement should be made that reference is made to the main text for the definition of those acronyms.
Page 2, first line below heading S1.2: Replace “is done, to” by “was done to”.
Page 2, third line below heading S1.2: Replace “Table S3” by “Table S2”.
Page 2, heading of Table S2: There is something wrong with the equation in this heading. There is “Faw” at both sides of the “=” sign.
Page 2, third last line: Replace “is applied” by “was applied”.
Page 3, first line: Replace “are initialised” by “were initialised ”.
Page 6, caption of Fig. S2 and within the figure: As indicated by Referee #3, “PM10” should be replaced “TSP”.
Page 8, first line: Replace “are shon” by “are shown”.
Page 8, heading of Table S4: See comment above with regard to the term “a.e.d.”.
Page 9, fourth line: Replace “than our ” by “as our ”.
Page 9, line 18: Replace “were very” by “was very”.
Page 9, line 19: Replace “also SM Fig. S5a” by “also Fig. S4a ”.
Page 10, first line: Replace “were adopted from” by “were adopted”.
Page 10, third line: Replace “Fig. S4” by “Fig. S3”.
Page 11, first line: Replace “Fig. 4” by “Fig. 3”.
Page 12, second line: Replace “Fig. S5” by “Fig. S4”.

Some corrections and clarifications are still needed.

Main text:
A few acronyms should still be defined. This is the case for the indices p and g of c, OM (it is first used in line 165, but only defined in line 184), Fem, and ISS (it is first used in line 267, but only defined in line 285).
Lines 62-65: In contrast to what is written in the reply, this paragraph was not rephrased. It should be.
Line 173: It is still unclear what the difference is between “cp” and “cTSP”.
Line 235: Replace “supplementary material (SM)” by “SM”; “SM” is defined in line 70.
Lines 360-364, further in the main text, and also in the Supplementary Material: Figure captions should be below figures instead of above.

Supplementary Material:
Page 9, line 9: Replace “also SM Fig. S4a” by “also Fig. S4a”.

The main text is OK now, but there are problems with the Supplementary Material. It figures did not come out.
