One of the recent approaches for improving the understanding of the aerosols effects on climate, based on ground-based observations, consists in the combination of active and passive remote sensing techniques, namely lidar and sun-photometer. The Lidar/Radiometer Inversion Code (LIRIC) combines the multiwavelength lidar with sun/sky photometry for the retrieval of particle microphysical properties separately for fine- and coarse-mode particles (Chaikovsky et al. 2008) and also particle optical properties. LIRIC uses profiles of backscattered lidar signals at 355, 532 and 1064 nm and AERONET photometer retrieval products (column-integrated particle size distribution, complex refractive index and other radiative properties). From them, a height-resolved dataset of microphysical and optical properties is created which is in agreement with the respective column-integrated sunphotometer observations. After an exhaustive evaluation (Wagner et al., 2013; Granados-Muñoz et al., accepted), a set of case studies with different aerosol types (namely anthropogenic pollution layers, forest fires smoke and desert dust) observed during 2011 and 2012 are presented which were observed over the EARLINET/AERONET southern Iberian stations of Évora (Portugal) and Granada (Spain).
