Online published on 2 February, 2019. Abstract Carbon dioxide is one of the most important greenhouse gases that is increased in atmosphere by effect of human. These rates increase in the winter season while less when the plant began to grow, where withdraws this gas by photosynthesis. CO2 is closely related to several elements of climate. CO2 meter device was used at Mustansiriya station for the purpose to measure concentration of gas during the winter season for the period (14/12/2015 to 27/3/2016), before rain fell by observing the weather situation, 14 rain cases were recorded during this period. Rainfall data is measured use the automatic weather station located in the Department of Atmospheric Sciences, Collage of Science. The result shows that increasing in concentrations of gas that has been measured about the natural gas, where the concentration of CO2 initial at the beginning of the rainy season is up to 450ppm at the end of the winter, while it was about 350ppm, External gas ratios by washing was high whenever the rainstorm is strong. The intensity of the gas fux is also increased by increasing the rain intensity I, so the rainy winter of Baghdad reduced the percentage of CO2 in the atmosphere.
