Towards Operational Earth System Monitoring, Assimilation and Prediction Systems

2000

Specific goals 1
Specific Goals (1)

  • Acquire satellite data for a few chemical species (ozone, NOx, CO, CH2O), assess the quality of these data, and implement these data into the GEMS 4-D var assimilation system.

  • Use 3 existing chemistry transport models at ECMWF to provide the chemical source terms required by the assimilation system, and calculate the concentration of chemical compounds that are not assimilated by the ECMWF system.


Specific goals 2
Specific Goals (2)

  • Develop prototype user services including

    • predicted global distributions of reactive chemical compounds in the troposphere and stratosphere

    • surface UV forecasts,

    • volcano plume forecasting system

  • Evaluate reanalysis simulations and assess the quality of the predictions using routine chemical observations and event-based case studies.

  • Provide information for regional air quality predictions

The 3 chemical transport models
The 3 Chemical Transport Models

  • MOCAGE: Multi-scale CTM developed by Meteo-France (Peuch et al., 1999) using the RACM scheme to describe the chemistry of the troposphere. Advection is treated by a semi-Lagrangian algorithm.

  • TM5: CTM introduced in the Netherlands by KNMI with a tropospheric module adopted from the CBM4 scheme. Uses the Prather scheme for advection. Includes two-way nested zooming capability over Europe. (Krol et al., 2004)

  • MOZART-3: CTM developed by NCAR and MPI-M. Uses its own chemical scheme and treats advection using the Lin and Rood algorithm (Brasseur et al. 1998; Horowitz et al., 2003; Kinnison et al., 2005).
