I am pleased to accept the revised manuscript subject to the following technical corrections.
- In the paper, the term 'photolysis rate' is frequently used incorrectly instead of 'photolysis frequency' (s-1). Alternatively, it could be called 'photolysis rate coefficient'. A photolysis rate (molec. cm^-3 s-1) would be the product of the photolysis frequency of a compound times its concentration.
- I suggest to use lower-case j as a symbol for photolysis frequencies, as it denotes a reaction rate coefficient. Rate coefficients (k) are generally denoted by lower case letters. See, for example Shetter et al., JGR, VOL. 108, NO. D16, 8544, doi:10.1029/2002JD002932, 2003. (Though, I realize that lower- and upper-case for j-values has not been consistently used in past atmospheric literature).
- Referee #2 is asking for the specific atmospheric conditions for which photolytic lifetimes were calculated ("Lines 22-23. The specific atmospheric conditions that the photolytic lifetimes were calculated for should be stated."). In addition to latitude and date (or alternatively solar zenith angle), you could mention the assumed albedo and total ozone column. What were the assumptions for atmospheric aerosols and clouds?
