The data include aerosol optical depth spectra and water vapor columns. In the case of the ACE 2 airborne data, they also include vertical profiles of aerosol extinction spectra and water vapor concentrations, derived by vertically differentiating smoothed profiles of optical depth and water vapor column content. Details regarding file names and other specifics are in John's and Beat's emails.
