Abstract

In this chapter, the trends and temporal variations of four major greenhouse gases (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6)) measured at Hegyhátsál, Hungary, are analyzed on the basis of in situ and flask measurements. The long-term trends observed closely follow the global tendencies. The relatively small positive offset can be attributed to the European anthropogenic sources. The seasonal cycles are basically governed by that in the atmospheric mixing; however, in the case of CO2 and N2O, it is also modulated by the temporal variation in the biological activity. A secondary maximum in SF6 mixing ratio in summer may indicate the additional contribution of the seasonally changing circulation pattern. The daily cycles are dominated by the diurnal variation in the vertical mixing of the atmosphere. However, in the case of CO2, the diurnal cycle in the biospheric uptake/release is the governing process, especially in the growing season. The lack of a diurnal cycle in the mixing ratio of the exclusively anthropogenic SF6 indicates that there is no notable anthropogenic activity in the influence area of the station, which supports that Hegyhátsál tall tower can be-considered to be a rural monitoring site as free from direct anthropogenic pollution as it is possible in Central Europe.
