A general parallelization approach to improve computation efficiency in a global chemical transport model (GEOS-Chem)
MPI OpenMP parallelization GEOS-Chem modeling performance
2017/8/9
Despite increasing processing power of systems, sequential programs have limitations to achieve corresponding performance gains. Parallelization of sequential programs can exploit the computation pote...
Lightning NOx emissions over the USA constrained by TES ozone observations and the GEOS-Chem model
Lightning NOx TES ozone observations GEOS-Chem model
2010/1/18
Improved estimates of NOx from lightning sources are required to understand tropospheric NOx and ozone distributions, the oxidising capacity of the troposphere and corresponding feedbacks between chem...
Inverse modeling and mapping US air quality influences of inorganic PM2.5 precursor emissions using the adjoint of GEOS-Chem
US air quality influences inorganic PM2.5 precursor emissions GEOS-Chem
2009/8/25
Influences of specific sources of inorganic PM2.5 on peak and ambient aerosol concentrations in the US are evaluated using a combination of inverse modeling and sensitivity analysis. First, sulfate an...
Implementation and evaluation of an array of chemical solvers in the Global Chemical Transport Model GEOS-Chem
Implementation evaluation array chemical solvers Global Chemical Transport Model GEOS-Chem
2010/2/5
This paper discusses the implementation and performance of an array of gas-phase chemistry solvers for the state-of-the-science GEOS-Chem global chemical transport model. The implementation is based o...
Regional CO pollution and export in China simulated by the high-resolution nested-grid GEOS-Chem model
Regional CO pollution high-resolution nested-grid GEOS-Chem model
2009/6/16
An updated version of the nested-grid GEOS-Chem model is developed allowing for higher horizontal (0.5°×0.667°) resolution as compared to global models. CO transport over a heavily polluted region, th...
We present the adjoint of the global chemical transport model GEOS-Chem, focusing on the chemical and thermodynamic relationships between sulfate – ammonium – nitrate aerosols and their gas-phase prec...
