This study focuses on the retrieval of lidar overlap functions at two wavelenghts (355 and 532 nm) for the lidar routinely operated at the EARLINET Granada station, placed in the southeastern Iberian Peninsula. For this aim, aerosol backscatter coefficients retrieved from both Raman and elastic lidar signals were used. The method is based on the fact that aerosol backscatter profiles derived from elastic signals suffer from incomplete overlap effect whereas those retrieved from Raman signals are unaffected. This article reports about the reproducibility of the lidar overlap functions under different atmospheric scenarios and also the impact of some features of the iterative process itself.
