Characteristics of Turbulence and Aerosol Optical and Radiative Properties during Haze–Fog Episodes in Shenyang, Northeast China

Abstract: The characteristics of turbulence in the planetary boundary layer (PBL) and the aerosol optical and radiative properties during haze and haze–fog mixed episodes on 22–27 January 2021, in Shenyang, a provincial city in Northeast China, were analyzed using meteorological and aerosol observations. During the haze episode, the hourly mean PM2.5 concentration reached a maximum of 337 µg m−3 and visibility decreased to 1.6 km. The PM2.5 concentration decreased gradually during the haze–fog mixed episode as a result … Show more

“…Additionally, the DnLWI on dusty days was higher than on non-dusty days (Figure 4c,d), which mainly depended on sky conditions (e.g., clouds, fog, smoke, blowing snow, smog, etc. ), air temperature, and air-water content [49,50]. Atmospheric inverse radiation often increases with higher air temperature, more water vapor in the air (affecting the atmospheric emissivity), and higher cloud cover.…”
