The GEOS-Chem tropospheric chemistry model — •Marco Scharringhausen1, Justus Notholt1, Thorsten Warneke1, and Daniel Jacob2 — 1Institut für Umweltphysik, Universität Bremen, Fachbereich Physik, Otto-Hahn-Allee 1, 28359 Bremen — 2Harvard University, Cambridge MA 02138-2901, USA
The GEOS-Chem Atmospheric Model is a tool for three-dimensional modelling of the tropospheric and lower stratospheric chemical composition. It is driven by meteorological data provided by the NASA Goddard Earth Observing System (GEOS). GEOS-Chem is a merge of the GEOS data fields, a chemical transport model and manifold chemistry routines, some of which are
- Sources and sinks of aerosols (anthropogenic/non-anthropogenic) - Burning of fossil fuels (anthropogenic) - Biomass burning (anthropogenic/non-anthropogenic) - Biological emissions (anthropogenic/non-anthropogenic) - Transport - Photolysis
The GEOS-Chem model is parallelized using OpenMP. As open source software, it is being developed and maintained by an world-wide community.
First results of the installation at the Institute of Environmental Physics (IUP) Bremen are presented. Model runs presented focues on the chemistry of CH4, CO and CO2. The model results are compared to measurements of several Fourier Transform Infrared Spectrometer instruments (FTIR) operated by IUP Bremen.
