TL;DR: The Influence of Stratosphere-Troposphere Exchange in a Changing Climate on Atmospheric Transport and Oxidation Capacity (STACCATO), recently funded by the European Union, provides a review of stratosphere-troposphere exchange (STE), with a focus on processes in the extratropics.

TL;DR: The REE distribution patterns of fir and spruce were almost identical, but differed profoundly from that of the other species, and in most cases, concentration ratios between species were a smooth function of the atomic number of the REE.

TL;DR: The chemical separation and characterization of six atoms of element 107 (bohrium, Bh), in the form of its oxychloride, is reported, finding that this compound is less volatile than the oxychlorides of the lighter elements of group VII, thus confirming relativistic calculations that predict the behaviour of bohrium to coincide with that expected on the basis of its position in the periodic table.

TL;DR: In this paper, the 7Be activity concentrations measured from 1996 to 1998 at four high-altitude stations, Jungfraujoch, Switzerland, Zugspitze, Germany, Sonnblick, Austria and Mt. Cimone, Italy, were analyzed in combination with a set of, meteorological and atmospheric parameters such as the tropopause height, relative and specific humidity and also in conjunction with 3D back-trajectories in order to investigate the climatological features of 7Be.

TL;DR: In-situ measurements of the airborne volcanic plume were performed both within ground-based monitoring networks and with a research aircraft up to an altitude of 6000 m a.s.l. as mentioned in this paper.
