The authors have reasonably addressed the comments of the two anonymous referees and they have modified their manuscript accordingly. However, the comments given below should be addressed and several alterations are needed for the Main text and Supplement before the manuscript can be published in ACP.

Main text:
Page 4, line 23: Replace ", other" by "; for other".
Page 4, line 24: Replace "and those" by "and for those".
Page 4, line 26: Replace "Organosulfates" by "For organosulfates".
Page 4, line 29: Replace "were calculated" by "was calculated".
Page 5, line 14: Replace "sulfur- containing" by "sulfur-containing".
Page 5, line 19: Replace "and elemental" by "and an elemental".
Page 5, line 23: Replace "were measured" by "was measured".
Page 6, line 12: Replace "are summarized" by "is summarized".
Page 6, line 13: Replace "select species" by "selected species".
Page 6, line 22: Replace "is shown" by "are shown".
Page 6, line 28: Replace "than m/z" by "than to m/z".
Page 7, line 24: "Nestorowicz et al." was published on 20 December 2018. Therefore, it should be updated here and on page 16 in the Reference list. Note also that the author list should be updated in that list.
Page 8, line 26: Replace "an SOA" by "a SOA".
Page 9, line 11: Reference is made here to Fig. S3, but this Figure does not exist. Should "Fig. S3" perhaps be replaced by "Table S3"?
Page 12, line 22: Reference is made here to Table S5, but this Table does not exist.
Page 14, lines 22-27: "Hansen, A. M. K., et al., 2014" should come before "Hansen, D. A., et al., 2003".
Page 17, line 6: Replace "Anal. chem." by "Anal. Chem.".
Page 18, line 13: Replace "in the Atmosphere" by "in the atmosphere".
Page 24, line 7: Replace "Nestorowicz et al. (in review)" by "Nestorowicz et al. (2018)".

Supplement:
Tables S2 and S4, heading, line 1: It says "n=26" here, but there are 32 chemical formulas listed in the Tables.

Short summary

This study examines anthropogenic influences on secondary organic aerosol at an urban site in Atlanta, Georgia. Organosulfates accounted for 16.5 % of PM_2.5 organic carbon and were mostly derived from isoprene. In contrast to a rural forested site, Atlanta's isoprene-derived organosulfate concentrations were 2–6 times higher and accounted for twice as much organic carbon. Insights are provided as to which organosulfates should be measured in future studies and targeted for standard development.
