Observation-constrained clear-sky direct radiative forcing of black carbon containing aerosols reveals distinct radiative regimes across urban Asia

Black carbon (BC) aerosols exert a strong yet uncertain influence on the atmospheric energy balance, yet their radiative forcing estimates remain poorly constrained. Current top-down and bottom-up approaches remain limited in resolving how microphysical evolution and column prope...

Dust radiative effects and impact on energy production over the Mediterranean Basin

Abstract. Atmospheric aerosols are among the key factors affecting the Earth’s radiation budget, playing a fundamental role in understanding climate forcing, feedback mechanisms, and their impact on future climate projections and on solar energy systems. More specifically, dust a...

Evaluation of smoke mass concentration within the PBL based on observations of fluorescence lidar with several discreet channels

Abstract. Elevated concentrations of smoke within the planetary boundary layer (PBL) represent a significant health hazard, making its monitoring essential. This study demonstrates that a multi-channel fluorescence lidar can effectively analyze smoke–urban aerosol mixtures and re...
