As the dominant anthropogenic greenhouse gas, Carbon Dioxide (CO2) is the most prominent
Greenhouse gas in Earth's atmosphere and plays a key role in earth's climate. It’s resulting more than 50%
of the global warming when all greenhouse gases (excepting water vapor) are added together. Since the
dawn of the Industrial Revolution, its concentrations increased over 110 ppmv. The troposphere CO2 have
been studied employing Atmosphere Infrared Sounder (AIRS), onboard NASA's Aqua Satellite, and data of
CO2 emission in Iraq during the period 2010 – 2011. The analysis for five dispersed stations shows the
seasonal variation in the CO2 fluctuated considerably observed between spring and autumn seasons. The
mean and the standard deviation of monthly CO2 was (391.77±4.55 ppm) for the entire period. The CO2 in
2011 values was higher than its values in 2010 at all stations throughout the period. The highest value that
occurred in this period was on March at Baghdad (396.32 ppm) and the lowest value was in September at
Basra (387.22 ppm). Elevation in CO2 values can be observed throughout the year over the congested urban
and Industrial area. The monthly CO2 maps for study area were obtained from the NASA-operated
GIOVANNI portal (http://disc.sci.gsfc.nasa.gov/giovanni). The AIRS data and the Satellite measurements
are able to measure the increase of the troposphere CO2 concentrations over different regions.
