Interactive comment on “A Complete Parameterization of the Relative Humidity and Wavelength Dependence of the Refractive Index of Hygroscopic Inorganic Aerosol Particles” by Cotterell et al

Reviewer #2 I have read the article “A Complete Parameterization of the Relative Humidity and Wavelength Dependence of the Refractive Index of Hygroscopic Inorganic Aerosol Particles” by the authors Cotterell et al. submitted to Atmos. Chem. Phys. Discuss. This paper provides the refractive indices for aerosol particles composed of salt and water using several atmospherically relevant salts as a function of relative humidity from 100% RH to the efflorescence of the salt. Several wavelengths in the visible were used and dispersion coefficients were derived to obtain the refractive index at intermediate values. The significance of the article is summarized in section 4 “these ...[data] represent the most comprehensive description of refractive index for atmospherically relevant inorganic aerosol, fully characterizing the RI variation with both visible wavelength[s] and RH”. I have only a few minor comments that should be addressed.
