# | Wavelength (nm) | Comment |
---|---|---|
1. | 240–400 | UFS1, UFS2, KS11 filters for comparison with MSU experiments (Tatiana-1, Tataina-2, and Vernov) |
2. | 270–380 | |
3. | > 600 | |
4. | 762.7 | TLE marker—atomic oxygen absorption line |
5. | 777.4 | Lightning marker—the brightest line in lightning spectrum, used for lightning detection in LIS ((Orville and Henderson 1984)) and convergence ((Sharkov et al. 2018)) experiments |
6. | 500.1 | Lightning marker—bright line in lightning spectrum and absent in sprite spectrum ((Milikh et al. 1998)) |
7. | 337 | N22P line—marker of low latitude and should absent in lightning spectrum due to ISUAL data |
8. | 391.4 | N\(_{2}^{+}\)1N—line of ionized atomic nitrogen |
9. | 427.8 | N\(_{2}^{+}\)1N present in aurora light and marker of ionization source (energetic charge particle flow) |
10. | 470.9 | |
11. | 690 | Meinel band—marker of high latitude and high energy of electrons involved into the process |
12. | 388.3 | Cyanogen (CN) emission, a spectral signature of lightning flashes with continuing current (monitoring of lightning that can cause forest fires ((Christian et al. 1983; Fuquay et al. 1967)). |
13. | 294 | Signature of extremely high altitude event (lines of N2(VK) system) |
14. | 313 | |
15. | 399.8 | N22P(1,4) analyzed by (Armstrong et al. 2000), in comparison to 427.8 nm and 470.9 nm lines |
16. | Without filter | Total emission of lightning or TLE measurements |
