An optical model originally developed at 532 nm is applied to the Ruby laser wavelength of 694 nm. Functional relationships resulting from the model allow estimates of stratospheric aerosol surface area, volume, extinction-to-backscatter ratio, extinction, and effective radius from single wavelength, Ruby-lidar measurements. These parametrizations are valid for global stratospheric sulphate aerosols and liquid polar stratospheric clouds. Relative errors of the estimates are in the range of 15–45% for surface area, 15–30% for volume, 20–35% for extinction-tobackscatter ratio and extinction, and 40–55% for effective radius. These errors are comparable to the ones characterizing direct, in situ techniques as optical particle counters. Comparisons with results of the original model at 532 nm are presented.
