They are examined in two groups as primary and secondary. Primary cosmic rays are very high-energy cosmic rays that can reach the earth directly and are usually composed of Hydrogen (Proton) or Helium (Alpha Particle) nuclei. As cosmic rays pass through the atmosphere, they collide with the gas atoms in the atmosphere, and in this case, the particle reacts and becomes other particles. In this case, cosmic rays with lower energy reaching the ground are secondary cosmic rays.). Primary cosmic rays can affect the reflection values of the images by affecting the electronic system (CCD) of the satellites. In the study, temporal variation in speckle values in radar images was compared with cosmic beam intensity data to examine this effect. In this study, the study area is selected from Baksan-Russia where there is a cosmic ray station. It is Located at 43.25 ° north latitude and 42.69 ° east longitude, the station has a cut-off rigidity value of 5.6 GV. Baksan Neutron Monitor has been operated since 2003 by the Russian Academy of Nuclear Physics Institute. For the data obtained between January 2015 and December 2019, the graph of the monthly median and cosmic ray intensity values were plotted. The correlation between noise and cosmic ray count is calculated as 72%. Google Earth Engine is used to derive the results.
