Chemistry/Transport Model Simulations for Aura Validation Experiments

Introduction:
We are running the Goddard stratospheric chemistry and transport model (CTM) for the purposes of planning and analysis of the Aura Validation Experiment (AVE). A set of standard diagnostic output plots are available here. Requests for special output format will be considered and suggestions are welcome.

Some details of the simulation:
Model meteorology (winds, temperatures, convective flux, etc.) are obtained from data assimilation at the Goddard Global Modeling and Assimilation Office (GMAO). Version GEOS-4 is used here. Off-line chemistry and transport with 3-hour average analyzed met data, including convection and diffusion in the troposphere, are run on a 2 x 2.5 degree grid with 28 vertical levels. The model run was initialized on 2004-08-25. A full representation of stratospheric chemistry is included, but application to the troposphere is limited. Polar stratospheric cloud processes are parameterized according to Considine et al., JGR, 2000. Forecast model chemical fields up to 4 days from analysis time are also done using GMAO forecast meteorology output every 6 hours.
