By combining active and passive remote sensing data with in-situ observations, a comprehensive study of aerosol distribution and impact of biomass burning on air quality and optical properties can be achieved. The analysis of different episodes based on measured concentrations and wind direction reveals long-range transport from different source regions.

Summary: In this study, the detection capability of spaceborne lidar under different atmospheric conditions was evaluated using simulated signals based on ground-based lidar measurements. The detection performance was evaluated in terms of signal-to-noise ratio, volume depolarization ratio, and attenuated color ratio. The optical parameters of clouds and aerosols were inverted using the Fernald method, and the effective signal of the spaceborne lidar was simulated. Simulation experiments were conducted by varying the cumulative laser pulse number and atmospheric conditions. The experimental results demonstrated the ability to detect cloud and aerosol layers with extinction coefficients above 0.3 km(-1) at night with a cumulative pulse number of 1000 and a vertical resolution of 15 m. In the daytime, moderate pollution aerosols and thick clouds could be easily identified with a cumulative pulse number of 10,000 and a vertical resolution of 120 m.

Summary: The aerosol measurements from lidar and PM10 samples around the European Arctic site of Ny-Alesund during late winter-early spring 2019 showed time-independent values for various aerosol parameters. Despite erratic changes in daily nss-SO42- concentration at different sites, seasonal average basis results were consistent, indicating potential advection of nss-SO42- mainly in the lowest free troposphere.

Summary: This study introduces an aerosol-optics model for water-coated marine aerosols that takes into account irregularities in the geometry of dry salt particles and simulates the processes of water adsorption, salt dissolution, and rearrangement of the liquid mantle. The model can be adjusted to generate size-shape distributions, which are then used to compute various optical parameters. The results show that the model performs better than homogeneous superellipsoids.

Summary: This paper introduces and realizes a 3D imaging method based on compressed sensing technology and dual-frequency laser phase ranging. The time-domain light intensity signal collected by a single-point detector is used for two-dimensional range reconstruction using compressed sensing algorithm. By solving the phase information of the two-dimensional spatial distribution in the time-domain signal, the 3D image information of the target scene is inverted, achieving the effect of scan-free 3D imaging. The feasibility of the system is verified through simulations and different reconstruction algorithms are compared. A non-scanning 3D imaging experimental platform is designed and built, successfully reconstructing 3D images of multiple objects with 32x32 resolution.

Summary: This study reports on the first aerosol profiling campaign in the Paraiba valley, an important hub connecting the two largest Brazilian metropolitan areas. Ground-based lidar measurements provide a detailed description of the particulate material in the local atmosphere, revealing the presence of aerosols in multiple atmospheric layers. The study also suggests the possible long-range transport of aerosols from biomass burning areas in South America.

Summary: By conducting airborne backscatter lidar and in-situ measurements over Siberia, we were able to identify six aerosol types including dusty aerosol mixture, gas flaring emissions, fresh and aged forest fire plumes, urban emissions, and long range transport of urban emissions from Northern China. The altitude range and aerosol optical properties varied among different aerosol types, with BC concentrations generally higher in flaring plumes compared to urban emissions. Additionally, comparisons between aged and fresh plumes showed an increase in aerosol optical depth and particle size for aged forest fire plumes.

Summary: This study investigates the turbulent properties of long-range-transported Saharan dust layers using airborne backscatter and water vapor lidar measurements for the first time. The analysis of two case studies shows that turbulence inside the transported dust layers follows predicted slopes and small Richardson numbers confirm the turbulent nature of the Saharan air layers. These results support the hypothesis that turbulence inside dust layers helps to keep large mineral dust particles aloft after long-range transport.

Summary: This study utilized lidar technique to investigate the vertical distribution of aerosol particles in Ioannina, Greece during winter. The results showed that biomass burning activities were the main source of winter air pollution in the region. By measuring and analyzing aerosol particles, it was found that most of the aerosol layers in the lower free troposphere were fresh biomass burning particles, with wood burning being the primary contributor.

Summary: The automated aerosol type classification method, SCAN, is independent of optical properties and not affected by overlapping values, making it valuable for classifying different aerosol mixtures. Compared to other methods like NATALI and MD, SCAN shows lower percentage of unclassified layers and is capable of classifying aerosol layers based on even single lidar signals.
