Impact of biogenic very short-lived bromine on the Antarctic ozone hole during the 21st century
(Copernicus Publications, 2017-01)
Active bromine released from the photochemical decomposition of biogenic very short-lived bromocarbons (VSL_Br ) enhances stratospheric ozone depletion. Based on a dual set of 1960-2100 coupled chemistry-climate simulations ...
Modelling the Inorganic Bromine Partitioning in the Tropical Tropopause over the Pacific Ocean
(Copernicus Publications, 2017-08)
The stratospheric inorganic bromine burden (Bry) arising from the degradation of brominated very short-lived organic substances (VSL org ), and its partitioning between reactive and reservoir species, is needed for a ...
Bromine partitioning in the tropical tropopause layer: implications for stratospheric injection
(Copernicus Publications, 2014-12)
Very short-lived (VSL) bromocarbons are produced at a prodigious rate by ocean biology and these source compounds (SGVSL), together with their inorganic degradation products (PGVSL), are lofted by vigorous convection to ...
Intercomparison between surrogate, explicit, and full treatments of VSL bromine chemistry within the CAM-Chem chemistry-climate model
(American Geophysical Union, 2021-02)
Many Chemistry-Climate Models (CCMs) include a simplified treatment of brominated very short-lived (VSLBr) species by assuming CH3Br as a surrogate for VSLBr. However, neglecting a comprehensive treatment of VSLBr in CCMs ...
Ocean biogeochemistry control on the marine emissions of brominated very short‐lived ozone‐depleting substances: A machine‐learning approach
(American Geophysical Union (AGU), 2019-11)
Halogenated very short lived substances (VSLS) affect the ozone budget in the atmosphere. Brominated VSLS are naturally emitted from the ocean, and current oceanic emission inventories vary dramatically. We present a new ...
BrO and Bry profiles over the Western Pacific: Relevance of Inorganic Bromine Sources and a Bry Minimum in the Aged Tropical Tropopause Layer
(Copernicus Publication, 2017-07)
We report measurements of bromine monoxide (BrO) and use an observationally constrained chemical box-model to infer total gas phase inorganic bromine (Bry) over the tropical Western Pacific Ocean (tWPO) during the CONTRAST ...
Seasonal impact of biogenic very short-lived bromocarbons on lowermost stratospheric ozone between 60° N and 60° S during the 21st century
(Copernicus Publications, 2020-07)
Biogenic very short-lived bromocarbons (VSLBr) currently represent ∼25 % of the total stratospheric bromine loading. Owing to their much shorter lifetime compared to anthropogenic long-lived bromine (e.g. halons) and ...
