Effect of Carbon Dioxide, Methane and Nitrous Oxide with TCO and Solar Flux on the Earth’s Stratosphere Temperature in Mid-Latitude Region for Period 2000-2018

Abstract

Abstract The stratosphere is the second layer of the atmosphere and the important of this layer is to contain the ozone layer which absorbs the UV radiation from the Sun. The main objective of this research is to study the effect of GHGs and TCO on the temperature of stratosphere layer in the presence of influence of solar radiation in mid-latitude region, specifically capital Beijing (latitude 40°N; longitude 116°E) in China are taken as a study case, because it is the most city in the world that emits greenhouse gases for the period (2000-2018) selected in this research. The data for GHGs (carbon dioxide, methane and nitrous oxide) are taken from Emissions Database for Global Atmospheric Research (EDGAR), the monthly average data for the total column ozone and temperature are taken from the European Centre for Medium Range Weather Forecasts (ECMWF). While the data for the solar radiation is taken from the NASA Goddard Institute for Space Studies. The data for Sunspot number is taken from Sunspot Index and Long-term Solar Observations (SILSO), all these data are taken for the period (2000-2018) above the capital Beijing. From data analysis and results it found that there is a cooling effect on the stratosphere layer due to increase in greenhouse gases and decrease in the total column ozone, as well as the decreasing in solar radiation leads to this cooling.
