Jennie L. Thomas,Jennie L. Thomas,Jochen Stutz,Barry Lefer,L. G. Huey,K. Toyota,K. Toyota,Jack E. Dibb,R. von Glasow +8 more
TL;DR: In this article, a new detailed one-dimensional snow chemistry module has been coupled to the 1-D atmospheric boundary layer model MISTRA, which includes heat transport in the snowpack, molecular diffusion, and wind pumping of gases in the interstitial air.
Journal ArticleDOI
GEM-AQ, an on-line global multiscale chemical weather modelling system: model description and evaluation of gas phase chemistry processes
Jacek W. Kaminski,Lori Neary,Joanna Struzewska,J. C. McConnell,A. Lupu,J. Jarosz,K. Toyota,Sunling Gong,Jean Côté,Xiong Liu,Xiong Liu,Kelly Chance,Andreas Richter +12 more
TL;DR: In this article, Tropospheric chemistry and air quality processes were implemented on-line in the Global Environmental Multiscale weather prediction model, GEM-AQ, which was developed as a platform to investigate chemical weather at scales from global to urban.
Journal ArticleDOI
Analysis of reactive bromine production and ozone depletion in the Arctic boundary layer using 3-D simulations with GEM-AQ: Inference from synoptic-scale patterns

TL;DR: In this paper, an online air quality model, GEM-AQ, with gas phase and heterogeneous reactions of inorganic bromine species and a simple scheme of air-snowpack chemical interactions implemented for this study is used.
Journal ArticleDOI
Air–snowpack exchange of bromine, ozone and mercury in the springtime Arctic simulated by the 1-D model PHANTAS – Part 1: In-snow bromine activation and its impact on ozone
TL;DR: In this article, a one-dimensional model that simulates multiphase chemistry and transport of trace constituents from porous snowpack and through the atmospheric boundary layer (ABL) as a unified system is presented.
