ABSTRACT: Today global warming has become one of
the most important concerns of environmental science. The redundancy of
greenhouse gases in the atmosphere is known as a major factor in this
phenomenon. These gases contain water vapor, carbon dioxide, methane, nitrous oxide,
and ozone. The CO2gas is one of their most effective among
these gases. According to scientific warnings, the amount of CO2gases
in the atmosphere has increased by 40% to 45% over the last 50 years. Reducing
the abundant gas in the atmosphere requires a good knowledge of related factors
involved, including sources that emit gases into the atmosphere and sinks that
absorb the gas from the atmosphere. The amount of CO2gas in
the atmosphere has been accurately measured in previous years with great certainty.
But the predicted values of emissions from sources and removals by sinks have
large ambiguities. As studies show, even the computed residuals trends (which
is obtained by subtracting the amounts of sinks from sources) strongly disagree
with the trends of the existence of CO2in the atmosphere. This
study as a preliminary review, proposes a method to identify the locations of
sources and sinks of carbon dioxide using global statistical information and
adding spatial analysis approaches. By applying this method to the data
observed from 2000 to 2011 and the extraction of likely sources and sinks, the
region of the Black Sea, near Romania recognized as one of the strong points
issued and Bukit Kototabang near Indonesia acknowledged as an Impressive CO2absorption
zone.
