Short summary
Lidar ratio is a key parameter for the aerosol characterization using satellite remote-sensing platforms as CALIOP. However, there are important differences in the values reported in the bibliography. The geographic characteristics of the IARC observatories location and a 10-year data series allow us to make a unique study of the mineral dust in the Saharan air layer. We report lidar ratios at 523 nm of 49 ± 6 sr and 50 ± 11 sr obtained by two different methods.
