This dataset provides the GARRLiC micro-physical and optical retrieved properties, based on combined lidar and photometer measurements. It covers the Jan-May period (excluding the data related to the May campaign and reported in the companion dataset) as of interest for the investigation of COVID-19 restriction and relaxation actions. Aerosol lidar preprocessed data analysed using the Single Calculus Chain (SCC) are used here, with no further quality control and checks apart the check that aerosol optical properties are obtained using such signals. Being only the data analysed with SCC, this dataset corresponds only to a subset of the aerosol optical profiles collected (https://doi.org/10.21336/gen.w3w1-j222). Photometer data used as inputs are the AERONET/NASA Aerosol Optical Depth (AOD) level 1.5 version 3 and the Almucantars (ALM) radiances version 3 products. The GARRLiC software uses internally the GRASP algorithm version 0.8.1. The generated products have the v2.11 version.
