Abstract. We derive an explicit (i.e. non-iterative) formula for the retrieval of the overlap function in an aerosol lidar with both elastic and Raman N2 or/and O2 channels used for independent measurements of aerosol backscatter and extinction coefficients. The formula requires only the measured, range-corrected, elastic and the corresponding Raman signals, plus an assumed lidar ratio. We assess the influence of the lidar ratio error in the overlap function retrieval and present retrieval examples.

Short summary
In this paper, an explicit formula for recovering the overlap function of an aerosol lidar system is presented. It makes use of the elastic and Raman channels of the lidar. Some considerations are made about assumptions made on lidar ratio value. Results are presented for two measurements.
