ED: Publish subject to technical corrections (26 Jan 2018) by Farahnaz Khosrawi

Dear authors,

I am pleased to inform you that your paper is accepted for publication in ACP after the following technical corrections listed below have been made.

Best regards, Farahnaz Khosrawi

Technical corrections:
- P2, L20: "much-reduced" should read "much reduced".

- P2, L29: Coordinates on some occasions are given with a semicolon in between and in other occasions with a comma. This should be done one way or the other consequently.

- P3, L12: Same with U.S.A and USA. Use one or the other writing consequently throughout the manuscript.

- P4, L3: "AURA" should read "Aura".

- P4, L14: write "of the 1991 Pinatubo eruption".

- P4, L15: "larger" should rather be "stronger".

- P4, L26: "including accounting" --> either "including" or "accounting" is obsolete.

- P5, L10: "was input" should be replaced by "initialised" or "prescribed".

- P5, L14: "Simulations were started......"

- P5, L19: add "a" so that it reads "This is nevertheless a common methodology.....".

- P6, L3: it should read "injected by the Sarychev eruption....."

- P7, L21: "nucleii" should read "nuclei".

- P7, L21: add " nuclei" so that it reads in the parentheses (nuclei, N).

- P7, L31: add "the" so that it reads "on board the Swedish satellite Odin".

- P8, L3: skip "Results" so that it just reads in "Section 3.4".

- P11, Figure 3 caption: add in both instances a comma before "respectively".

- P12, L10: "13-14-day" should read ""13-14 day".

- P12, L18: plural? Thus "components"?

- P14, L1: "particle size ranges" rather than "particulate size ranges".

- P15, L13: "particle diameters" rather than "particulate diameters".

- P15, L13: It should read "further below in Section 3.5".

- P15, L25: Should be plural, thus "plumes"

- P18, L23: space is missing between "Fig" and "A2".

- P24, L5: "predicted that......" and it should read "reached up to 4% in the lowermost stratosphere in summer time/early fall".

- P25, L2: rather "to complement" than "to supplement".

- P25, L9: "size-bins" should read "size bins".

- P26, l7: it should read " reaching up to......"

- P26, L18: It should read "Our simulations are based on........".

P27, L1: skip "have".

P27, L5: rather " agreement" than "accordance".

Short summary

We quantify the chemical and microphysical effects of volcanic SO₂ and HCl from the June 2009 Sarychev Peak eruption using a comprehensive aerosol–chemistry model combined with in situ measurements and satellite retrievals. Our results suggest that previous studies underestimated the eruption's atmospheric and climatic impact, mainly because previous model-to-satellite comparisons had to make assumptions about the aerosol size distribution and were based on biased satellite retrievals of AOD.
