Abstract—

Aerosol layers with different scattering and absorption properties are studied on the basis of the data of multifrequency sounding. The effect of air advection on the aerosol optical and microphysical parameters in the lower and middle troposphere is analyzed. It is revealed that the low values of the extinction and backscattering coefficients, as well as the imaginary part of the refractive index and mean geometric radius of fine particles are observed at the north transfer direction, and the high values of these parameters are at the south direction. On the contrary, the lidar ratio and the contribution of fine fraction into the total concentration of particles decrease when the direction has been changed from north to south.

对流层气溶胶层：平流方向变化时气溶胶参数变化的特殊性

摘要—

根据多频探测数据，研究了具有不同散射和吸收特性的气溶胶层。分析了空气对流对对流层中低层气溶胶光学和微物理参数的影响。结果表明，在北移方向上观察到消光系数和后向散射系数的值较低，以及虚部的折射率虚部和平均几何半径，而在南侧则观察到这些参数的较高值方向。相反，当方向从北向南改变时，激光雷达比和细小部分对颗粒总浓度的贡献降低。
