We describe a method for joint analysis of the night-sky snapshots and total electron content (TEC) variation maps and present a dynamic spatiotemporal configuration of the TEC variation intensity in the ionospheric airglow region in the red line of atomic oxygen (λ = 630 nm) stimulated by high-power radio waves from the Sura facility. The measurements were performed on the 29th of August, 2016. Two-dimensional TEC variation maps were plotted according to a network of 30 GNSS stations located within a radius of 700 km from the Sura heater. It is shown that the region of the maximum brightness of the artificial ionospheric airglow spot is spatially localized in the region of the minimum intensity of TEC variations, while the region of the maximum intensity of TEC variations corresponds to the region of the minimum brightness of the artificial airglow spot. Quantitative estimates for a cavity with reduced electron density in the artificial airglow region, which forms after the Sura pump wave is switched on, vary in the range ΔNe/Ne ≈ 4–9%, where Ne is the electron density and ΔNe is its variation in the cavity. The proposed experimental technique eliminates the limitations associated with the need for a navigation satellite to flyby directly over the main lobe of the Sura antenna pattern, which significantly increases the chances of successful simultaneous measurements of TEC variations and artificial ionospheric airglow in the 630 nm line.

基于 630 nm 线夜空快照和总电子含量变化图联合分析的高功率无线电波引起的电离层人工气辉区的动态变化

我们描述了一种联合分析夜空快照和总电子含量 (TEC) 变化图的方法，并展示了原子氧红线 (λ = 630 nm) 电离层气辉区域中 TEC 变化强度的动态时空配置) 受到来自苏拉设施的高功率无线电波的刺激。测量于 2016 年 8 月 29 日进行。根据位于 Sura 加热器 700 公里半径内的 30 个 GNSS 站网络绘制二维 TEC 变化图。结果表明，人工电离层气辉光斑亮度最大的区域在空间上定位于TEC变化强度最小的区域，而TEC变化的最大强度区域对应于人工气辉点的最小亮度区域。在开启 Sura 泵浦波后形成的人工气辉区域中电子密度降低的腔的定量估计在 ΔNe/Ne ≈ 4-9% 范围内变化，其中 Ne 是电子密度，ΔNe 是其变化腔中。所提议的实验技术消除了与导航卫星需要直接飞越 Sura 天线模式主瓣相关的限制，这显着增加了成功同时测量 630 nm 线中 TEC 变化和人工电离层气辉的机会。打开 Sura 泵浦波后形成的 ΔNe/Ne ≈ 4–9% 范围内变化，其中 Ne 是电子密度，ΔNe 是其在腔中的变化。所提议的实验技术消除了与导航卫星需要直接飞越 Sura 天线模式主瓣相关的限制，这显着增加了成功同时测量 630 nm 线中 TEC 变化和人工电离层气辉的机会。打开 Sura 泵浦波后形成的 ΔNe/Ne ≈ 4–9% 范围内变化，其中 Ne 是电子密度，ΔNe 是其在腔中的变化。所提议的实验技术消除了与导航卫星需要直接飞越 Sura 天线模式主瓣相关的限制，这显着增加了成功同时测量 630 nm 线中 TEC 变化和人工电离层气辉的机会。
