Abstract

This study examine and analyze the amount of infrared radiations from top of the atmosphere using the NASA CERES Ordering tool data and other techniques. These radiations are responsible for the excessive heat waves in the upper atmosphere. Collected the data from the website with the help of NASA satellite named EBAF 4.2. The data barred into clear and all-sky monthly data. Used panoply software first to convert the NC file to CSV which is readable for excel. Then mark the maximum values and average of months and do the graphical analysis after the daily data conversion which is provide the information of the graph starting and ending and the difference between the values of all-sky and clear sky. In the end, concluded that the hotter years have higher IR flux values at that upper atmosphere just like 2014 and some other years, and these affected due to some major factors that discussed, such as cloud cover, surface temperature, greenhouse gas variations etc. Clouds that are present in the higher altitude known as the cirrus clouds absorb incoming radiation. The earth varying temperature controlled by incoming and outgoing radiations and another factor is greenhouse gas variation in the surface temperature.
