Özet

According to the maps produced by Japan Meteorological Agency, the raising rate around the Marmara Sea in Turkey is in average higher than Mauna Loa Observatory. As clean air in the sense of low concentrated CO2 is essential for basic requirement of live, a test study has been performed. Istanbul Technical University main campus in Istanbul/Turkey was selected as study area. It is located near by the heart of the commercial area with the approximate population of 30K including students and stuff. At the 80's, the neighborhood of the campus was totally covered with the forestry areas and small buildings which were converted to skyscrapers later on. The area now is housing many national and international companies in these huge skyscrapers at the northern part adjacent with a road of high traffic intensity. The other parts of the campus are either surrounded by squatter's house or roads which can be classified as heavy traffic. As the indoor air quality is directly depend on to outdoor gas component, the study focused to find out the distribution of Carbon dioxide levels in and around the campus. GIS based distribution maps were realized using daily measured parameters in the campus on 30 stations. GIS based spatial analyses have been carried out to display the distribution level of the Carbon dioxide concentration. CO2 concentration comparisons with different areas have been made.
