Abstract

The results of two-frequency lidar sounding of the atmosphere at the Kamchatka lidar station (52°58′17″ N, 158°15′07″ E) are presented. The scattering signals were recorded in the altitude range 25–600 km. Lasers with radiation at wavelengths of 532.08 and 561.106 nm were used. The aerosol formation in the middle atmosphere and resonance scattering by excited atomic nitrogen and oxygen ions in the upper atmosphere are studied. Pronounced light-scattering layers have been revealed at altitudes of 200–400 km. Their appearance is due to the presence of excited atomic oxygen and nitrogen ions. The difference in signal values at two wavelengths is discussed. A way of signal generation is suggested; signal values at different wavelengths are estimated.

摘要

给出了堪察加激光雷达站（52°58'17“ N，158°15'07” E）大气的两频激光雷达探测结果。在25-600 km的海拔范围内记录了散射信号。使用辐射波长为532.08和561.106 nm的激光器。研究了中层大气中的气溶胶形成以及高层大气中被激发的原子氮和氧离子引起的共振散射。在200–400 km的高度已经发现了明显的光散射层。它们的出现是由于存在激发的原子氧和氮离子。讨论了两个波长下信号值的差异。建议一种信号产生的方式。估计不同波长的信号值。
