Observations from Ground Level, what is involved in this scattering. It has become clear that noctilucent clouds are very thin and very sparse assemblies of scatterers. The cloud particles, whatever they may be, scatter light as individuals not as an assembly. Furthermore, there is a negligible amount of rescattering in the cloud作者: faction 時(shí)間: 2025-3-22 07:45
Spectrophotometry, and there are no obvious emission lines. The relative spectral distribution in the scattered light differs from that of sunlight and, in principle, this difference can be measured and used to estimate the size of the scattering particles. In practice, this is neither easy to do nor exact in applica作者: vertebrate 時(shí)間: 2025-3-22 11:47 作者: CHASM 時(shí)間: 2025-3-22 14:14 作者: 軍械庫(kù) 時(shí)間: 2025-3-22 19:52
