讨论了2016年春季和夏季在俄罗斯中部（55.2° N，37.5° E）进行的曙暮光背景和彩色（RGB）CCD矩阵全天空相机的多波测量的第一个结果。观测结果表明，在高达35公里的高度上，气溶胶散射的影响在光谱的长波部分（有效波长为624纳米的R波段）大大增强。分析的行为的天空颜色在轻期间的黄昏与津贴的臭氧吸收的Chappuis带，使之有可能恢复的角度依赖性的强度的气溶胶散射的光。这是用来确定对数正态分布的参数的气溶胶粒子在其大小的平均半径为0.08 μm和宽度为1.5-1.6平流层高度间隔。
The first results of multiwave measurements of twilight background and the all-sky camera with a color (RGB) CCD matrix conducted in the spring and summer of 2016 in Central Russia (55.2° N, 37.5° E) have been discussed. The observations reveal the effect of aerosol scattering at heights of up to 35 km, which is substantially enhanced in the long-wave part of the spectrum (R band with an effective wavelength of 624 nm). An analysis of the behavior of the sky color during light period of twilight with allowance for the absorption by ozone in the Chappuis bands make it possible to restore the angular dependences of the intensity of the aerosol scattering of the light. This is used to determine the parameters of the lognormal distribution of aerosol particles over their sizes with a mean radius of 0.08 μm and a width of 1.5–1.6 for the stratospheric height interval.
