The relationship between the concentration of carbon dioxide and wind using GIS

Carbon Dioxide (CO2) is the most prominent Greenhouse gas in Earth's atmosphere. The increasing of CO2 has a significant impact on climate change. The Wind is one of the important climatic factors in climate studies and are more important in explaining the climatic conditions of any site because they affect weather conditions. This study was aimed to use GIS techniques on knowing the effect of wind on the concentration of carbon dioxide through mapping of seasonal and annual concentration carbon dioxide and wind speed and direction over Iraq. Results showed that there is an inverse relationship between wind speed and the concentration of carbon dioxide. And high wind speeds seem to decrease the concentration of carbon dioxide and vice versa. In the spring, despite the high wind speed in the western region, the concentration of carbon dioxide is high, due of the desert nature of the western region, to human activity and abundance sources of CO2 at these regions and a shortage of CO2 removal with absence of the vegetation cover. Horizontal wind movement helps move carbon dioxide to other regions away from the source area and then mixes it with new winds, thus reducing the concentration of carbon dioxide.
