This work presents a field campaign oriented to filling the gap between the near-surface aerosol processes regarding aerosol radiative properties and connecting them with the atmospheric boundary layer (ABL), centering attention on the residual layer and the ABL transition periods. A Colibri Aerosol Lidar (CAL) instrument, based on the short-range lidar with high spatio-temporal resolution, was used for the first time in the ACTRIS AGORA facility (Andalusian Global Observatory of the Atmosphere) in Granada (Spain). This study showed the possibility of combining lidar and in situ measurements in the lowermost 150 m. The results address, on the one hand, the characterization of the short-range lidar for developing a method to find the calibration constant of the system and to correct the incomplete overlap to further data exploitation. On the other hand, relevant radiative properties such as the temporal series of the aerosol lidar ratio and extinction coefficient were quantified. The campaign was divided in three different periods based on the vehicular emission peak in the early mornings, namely, before, during, and after the emission peak. For before and after the emission peak data classification, aerosol properties presented closer values; however, large variability was obtained after the emission peak reaching the maximum values of extinction and a lidar ratio up to 51.5 ± 11.9 (Mm)−1 and 36.0 ± 10.5 sr, respectively. During the emission peaks, the values reached for extinction and lidar ratio were up to 136.8 ± 26.5 (Mm)−1 and 119.0 ± 22.7 sr, respectively.}, organization = {Spanish national projects PID2020-120015RB-100, PID2020-117825GB-C21, and PID2020-117825GB-C22 funded by MCIN/AEI/10.13039/501100011033}, organization = {Spanish project FEDER/Junta de Andalucía-Consejería de Transformación Económica, Industria, Conocimiento y Universidades/Proyecto C-EXP-366-UGR23}, organization = {University of Granada project PP2022.PP.34}, organization = {Europen project ATMO-ACCESS (grant agreement No. 101008004)}, organization = {Scientific Unit of Excellence: Earth System (UCE-PP2017-02)}, organization = {Spanish national project PID2020-120015RB-100 funded by MCIN/AEI/10.13039/501100011033}, organization = {Grant PID2021-128757OB-I00 (NUCLEUS project) funded by MCIN/AEI/10.13039/501100011033/ERDFA “A way of making Europe”}, organization = {Project PID2022-142708NA-I00, funded by MCIN/AEI/10.13039/501100011033/FEDER,UE}, organization = {Spanish ministry of research and innovation under the predoctoral program FPI (PRE2019-090827) funded by MCIN/AEI/10.13039/501100011033, FSE “El FSE invierte en tu futuro”}, organization = {National Council of Research and Development through Brazilian project 444761/2023-3}, publisher = {MDPI}, keywords = {Short-range lidar}, keywords = {Lidar ratio}, keywords = {ABL take-off}, title = {Synergy between Short-Range Lidar and In Situ Instruments for Determining the Atmospheric Boundary Layer Lidar Ratio}, doi = {10.3390/rs16091583}, author = {Bedoya Velásquez, Andrés Esteban and Ceolato, Romain and Titos Vela, Gloria and Bravo Aranda, Juan Antonio and Casans, Andrea and Patrón, Diego and Fernández Carvelo, Sol and Guerrero Rascado, Juan Luis and Alados Arboledas, Lucas}, }
