In this new version, the stratospheric model has been extended to the earth surface. Above the tropopause, the isentropic and cross-isentropic advection in CLaMS is driven by meteorological analysis winds and heating/ cooling rates derived from a radiation calculation. Below the tropopause, the model smoothly transforms from the isentropic to the hybrid-pressure coordinate and, in this way, takes into account the effect of large-scale convective transport as implemented in the vertical wind of the meteorological analysis. As in previous CLaMS simulations, the irreversible transport, i. e. mixing, is controlled by the local horizontal strain and vertical shear rates.Stratospheric and tropospheric signatures in the TTL can be seen both in the observations and in the model. The composition of air above approximate to 350 K is mainly controlled by mixing on a time scale of weeks or even months. Based on CLaMS transport studies where mixing can be completely switched off, we deduce that vertical mixing, mainly driven by the vertical shear in the tropical flanks of the subtropical jets and, to some extent, in the the outflow regions of the large-scale convection, offers an explanation for the upward transport of trace species from the main convective outflow at around 350 K up to the tropical tropopause around 380 K. 000058072 536__ $$0G:(DE-Juel1)FUEK406$$2G:(DE-HGF)$$aAtmosphäre und Klima$$cP22$$x0 000058072 588__ $$aDataset connected to Web of Science 000058072 650_7 $$2WoSType$$aJ 000058072 7001_ $$0P:(DE-Juel1)129123$$aGünther, G.$$b1$$uFZJ 000058072 7001_ $$0P:(DE-Juel1)129138$$aMüller, R.$$b2$$uFZJ 000058072 7001_ $$0P:(DE-Juel1)VDB65027$$ados Santos, F.
