Abstract. This article investigates the characteristics of laser pulse propagation in thin cloud layers using numerical modeling methods. The study primarily focuses on the influence of micro-physical properties of clouds on the polarization and transmission of laser pulses during re-mote sensing of the atmosphere. We use a dual approach that includes both direct numerical solutions of the radiation transfer equation and Monte Carlo simulations, exploring scenarios with and without polarization effects. Our results reveal important insights into how laser pulses interact with cloud layers, providing valuable conclusions for improving atmospheric sounding methods and remote navigation. The study explores the possibility of probing cloud layers using horizontal laser sounding from an aircraft, assessing the impact of cloud thick-ness and scattering properties on the behavior of both polarized and unpolarized light. Addi-tionally, the research emphasizes the importance of polarization analysis in structuring the diffuse field within clouds, potentially leading to the development of new atmospheric models based on observed propagation characteristics. The study contributes to a better understanding of atmospheric dynamics and supports the development of environmental monitoring methods and atmospheric physics.

Key words: numerical modeling, radiative transfer equation, thin cloud layers, polarization effects, Monte Carlo simulation
