13th international Polarized Neutrons for Condensed-Matter Investigations, PNCMI, online eventonline event, online event, 27 Jul 2021 - 30 Jul 20212021-07-272021-07-30
Proximity effects in superconductor(S)/ferromagnet(F) heterostructures with perpendicular magnetic anisotropy can manifest in various forms such as domain-wall-superconductivity [1] and the generation of long-ranged spin-triplet Cooper pairs [2]. Understanding the origin of such phenomena is the key for an application in fluxonic devices and in spintronics, respectively [3, 4]. [...]

Topological quantum materials have attracted enormous attention since their discovery due to the observed anomalous transport effects (ATE), which originate from the non-zero Berry curvature. Mn3Ge has gained special attention because anomalous transport effects can be studied below the Néel temperature (365 K), down to 2 K [1]. [...]

Investigating the roles of the Asian monsoon, the North American monsoon, and Hurricanes for efficient transport of chlorinated short-lived species to the UTLS based on in situ observations
EGU General Assembly, virtuellvirtuell, Austria, 19 Apr 2021 - 30 Apr 20212021-04-192021-04-30 [10.5194/egusphere-egu21-6136]
<p>Chlorinated very short-lived substances (Cl-VSLS) are not controlled by the Montreal Protocol but the recent emission increase of the Cl-VSLS CH<sub>2</sub>Cl<sub>2</sub> (Dichloromethane) and CHCl<sub>3</sub> (Chloroform) is believed to significantly increase the stratospheric chlorine loading from VSLS. Provided efficient transport of Cl-VSLS from the source region into the stratosphere further emission increases could ultimately even cause a significant delay of the predicted recovery date of the ozone layer to pre-1980 values [...]

New Fractional Release Factors, Ozone Depletion Potentials, and Lifetimes for Four Long-Lived CFCs: CFC-13, CFC-114, CFC-114a, and CFC-115
EGU General Assembly, virtuellvirtuell, Austria, 19 Apr 2021 - 30 Apr 20212021-04-192021-04-30 [10.5194/egusphere-egu21-4995]
<p>Knowing the stratospheric lifetime of an Ozone Depleting Substance (ODS), and its potential depletion of ozone during that time, is vital to reliably monitor and control the use of ODSs. Here, we present improved policy-relevant parameters: Fractional Release Factors (FRFs), Ozone Depletion Potentials (ODPs), and stratospheric lifetimes, for four understudied long-lived CFCs: CFC-13 (CClF<sub>3</sub>), CFC-114 (CClF<sub>2</sub>CCCLF<sub>2</sub>), CFC-114a (CCl<sub>2</sub>FCF<sub>3</sub>), and CFC-115 (C<sub>2</sub>ClF<sub>5</sub>) [...]

Organic and inorganic bromine measurements around the extratropical tropopause and lowermost stratosphere (Ex-LMS): Insights into transport pathways and total bromine
EGU General Assembly, virtuellvirtuell, Austria, 19 Apr 2021 - 30 Apr 20212021-04-192021-04-30 [10.5194/egusphere-egu21-10873]
<p>We report on measurements of total bromine (Br<sup>tot</sup>) in the upper troposphere and lower stratosphere (UTLS) taken from the German High Altitude and LOng range research aircraft (HALO) over the North Atlantic, Norwegian Sea and north-western Europe in September/ October 2017 during the WISE (Wave-driven ISentropic Exchange) research campaign. Br<sup>tot</sup> is calculated from measured total organic bromine (Br<sup>org</sup>) (i.e., the sum of bromine contained in CH<sub>3</sub>Br, the halons and the major very short-lived brominated substances) added to inorganic bromine (Br<sub>y</sub><sup>inorg</sup>), evaluated from measured BrO and photochemical modelling [...]

Study on Stratospheric Carbonyl Sulfide Transport and Chemistry using ‘Age of Air’
EGU General Assembly, virtuellvirtuell, Austria, 19 Apr 2021 - 30 Apr 20212021-04-192021-04-30 [10.5194/egusphere-egu21-5550]
<p>Carbonyl sulfide (OCS or COS) is the longest lived and the most abundant reduced sulfur gas in the atmosphere. As chemical loss of OCS in the troposphere is slow, it can reach the stratosphere, where it is &#160;photochemically oxidized and converted to stratospheric sulfate aerosol, being the largest source thereof in times of volcanic quiescence [...]

A case study on the impact of severe convective storms on the water vapor mixing ratio in the lower mid-latitude stratosphere

<p><br>Extreme convective events in the troposphere have not only immediate destructive impact on the surface, but can also influence the dynamic and composition of the lower stratosphere (LS). One of the impacts is the moistening of the LS [...]

The stratospheric Brewer-Dobson circulation inferred from age of air in the ERA5 reanalysis

<p>This paper investigates the global stratospheric Brewer-Dobson circulation (BDC) in the ERA5 meteorological reanalysis from the European Centre for Medium-Range Weather Forecasts (ECMWF). The analysis is based on simulations of stratospheric mean age of air, including the full age spectrum, with the Lagrangian transport model CLaMS, driven by winds and total diabatic heating rates from the reanalysis [...]

Asymmetry and pathways of inter-hemispheric transport in the upper troposphere and lower stratosphere
EGU General Assembly, virtuellvirtuell, Austria, 19 Apr 2021 - 30 Apr 20212021-04-192021-04-30 [10.5194/egusphere-egu21-6842]
<p>Inter-hemispheric transport may strongly affect the trace gas composition of the atmosphere, especially in relation to anthropogenic emissions which originate mainly in the Northern Hemisphere. This study investigates the transport from the boundary surface layer of the Northern Hemispheric (NH) extratropics (30-90<sup>o</sup>N), Southern Hemispheric (SH) extratropics (30-90<sup>o</sup>S), and tropics (30<sup>o</sup>S-30<sup>o</sup>N) into the global upper troposphere and lower stratosphere (UTLS) using simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) [...]
