Short summary
A severe winter haze event was observed with a Raman–Mie lidar, providing high-resolution profiles of the atmospheric vertical structure. By integrating collocated radiosonde and surface meteorological data, the key meteorological characteristics, influencing factors, and interaction mechanisms governing the formation and evolution of this haze event were analyzed. The solar radiation plays a significant role in haze development, with a strong coupling between aerosols and temperature.
