The book "The Neutral Upper Atmosphere" by S. N. Ghosh offers a comprehensive analysis of the upper atmosphere, based on findings obtained after World War II by Professor S.K. Mitra and other researchers. It discusses the results of ground-based and balloon-borne experiments that investigated phenomena such as daylight glows and the ozone layer. The discovery of ozone holes is highlighted as a significant advancement in the study of atmospheric processes. Additionally, the relationship between solar radiation and terrestrial phenomena is examined, particularly through the measurement of high-energy photons in various radiation ranges. This book brings together all this information and provides a deep insight into the dynamics of the neutral upper atmosphere.
