ABSTRACT

For cosmic radiation emerging from cosmic rays, the high energy particles is originating outside the solar system.The flux of incoming Cosmic Rays at the upper atmosphere is dependent on the Solar Activity. The influence of Solar Variability on Earth’s climate requires a solar variability, solar –terrestrial interactions and mechanisms determining the response of the Earth’s climate system, including solar irradiance variations on both decadal and centennial time scales and their relation to galactic cosmic rays. Cosmic Rays are also responsible for the continuous production of a number of unstable isotopes in Earth’s atmosphere. It can be used for validating magnetospheric field models during very severe storms.Measurements of the energy and arrival directions of the ultra-high-energy primary cosmic rays by the techniques of density sampling and fast timing of extensive air showers. Nanoparticles have large surface area to volume ratios and react rapidly in the atmosphere, commonly growing into particles large enough to interact with radiation and to have serious consequences for visibility and local, regional, and global climate. They also have potentially significant health effects. Gamma ray deriving from local supernovae could have affected cancer and mutation rates, and might be linked to decisive alterations in the Earth's climate. Nucleation mode particles accounts for the greatest number of atmosphericparticles and are found in high number concentrations near their sources.Atmospheric Nanoparticles are of growing interest to many investigators for two nanoparticles in technology and in the atmosphere Nanosized particles are a subgroup of atmospheric particles. Though humans have been exposed to Nanosized particles through‐ out their evolutionary stages, the respective exposure has dramatically increased over the last century due to contribution from various anthropogenic sources. The Airbourne particles are one of the most important pollutants of present times and their presence in the atmosphere has harmful effects both on human health and environment.
