Abstract

A three-year trace gas climatology of CO 2 and its stable isotopic ratios, as well as CH 4 ,N 2 O and SF 6 , derived from regular vertical aircraft sampling over the Eurasian continent is presented. The four sampling sites range from about 1° Et o 89°E in the latitude belt from 48° Nt o 62°N. The most prominent features of the CO 2 observations are an increase of the seasonal cycle amplitudes of CO 2 and d13C‐CO 2 in the free troposphere (at 3000 m a.s.l.) by more than 60% from Western Europe to Western and Central Siberia. d18O‐CO 2 shows an even larger increase of the seasonal cycle amplitude by a factor of two from Western Europe towards the Ural mountains, which decreases again towards the most eastern site, Zotino. These data reflect a strong influence of carbon exchange fluxes with the continental biosphere.

期刊介绍： Tellus B: Chemical and Physical Meteorology along with its sister journal Tellus A: Dynamic Meteorology and Oceanography, are the international, peer-reviewed journals of the International Meteorological Institute in Stockholm, an independent non-for-profit body integrated into the Department of Meteorology at the Faculty of Sciences of Stockholm University, Sweden. Aiming to promote the exchange of knowledge about meteorology from across a range of scientific sub-disciplines, the two journals serve an international community of researchers, policy makers, managers, media and the general public.
