Impact of Cosmic Rays in the Earth’s Atmospheric

In the present study, we used monthly data from the Grouped Solar Flare Index (GSF) and cosmic ray intensity (CRI) during solar cycles 22 to 24 in our correlative study. There is a strong and positive association between these three solar indices. We have employed sunspot numbers and clustered solar flares as trustworthy solar metrics. "The running cross-correlation" approach has been used in a comprehensive correlative analysis. Using statistical and correlative research, we find a strong negative association between solar activity and cosmic rays. Our findings corroborate the previous observations made for solar cycles 18 to 20. Compared to other solar activity indices, the observed cosmic ray modulation during these eras demonstrates why the (GSF) is a more appropriate solar activity measure than sunspot counts. When the most suitable solar activity index (GSF) is applied, the impacts are shown to be noticeably different in the four solar cycles 22 to 24, which calls for more short-term research. Furthermore, compared to other solar activity indicators, Earth's temperature is observed to follow decade changes in galactic cosmic ray flux and solar cycle duration more closely. The primary conclusion is that Earth's atmospheric conditions are influenced by the heliosphere's average state.
