Název v původním jazyce

Fossil fuel CO2 estimation by atmospheric 14C measurement and CO2 mixing ratios in the city of Debrecen, Hungary

Popis výsledku v původním jazyce

A field unit was installed in the city of Debrecen (East Hungary) during the summer of 2008 to monitor urban atmospheric fossil fuel CO2. To establish a reference level simultaneous CO2 sampling has been carried out at a rural site (Hegyhátsál) in Western Hungary. Using the Hungarian background 14CO2 observations from the rural site atmospheric fossil fuel CO2 component for the city of Debrecen was reported in a regional Hungarian?? scale. A well visible fossil fuel CO2 peak (10?15 ppm) with a maximum in the middle of winter 2008 (January) was observed in Debrecen air. Significant local maximum (20 ppm) in fossil fuel CO2 during Octobers of 2008 and 2009 was also detected. Stable isotope results are in agreement with the 14C based fossil fuel CO2 observations as the winter of 2008 and 2009 was different in atmospheric 13C variations too. The more negative 13C of atmospheric CO2 in the winter of 2008 means more fossil carbon in the atmosphere than during the winter of 2009.
