Variability ofSurface Ozone Concentrations(Monitoring needs long-term perspective) Meteorology(May 1993 – May 1997) Emissions(Fossil fuel 1995-1990) Martin G. Schultz, MPI Meteorology, HamburgGEMS proposal preparation meeting, Reading, 15-16 Dec 2003
Sub project elements • Data assimilation (UARS, AIRS, MIPAS, SCIAMACHY, GOMOS, SEVIRI, OMI, TES) – whole atmosphere columns, tropospheric columns, OT/LS layers • CTM simulations (MOZART, ARPEGE, TM5) • Integration/Validation • Provision of boundary conditions Martin G. Schultz, MPI Meteorology, HamburgGEMS proposal preparation meeting, Reading, 15-16 Dec 2003
Contribution of KNMI to Reactive Gases (1) • Experience with ozone data assimilation at KNMI - Operational ozone assimilation (since 2000) - Ozone and UV forecasting - Reanalysis - 7 years GOME data set - Radiance assimilation • Improved ozone retrievals for UV-Vis spectrometers - GOME - SCIAMACHY - OMI - GOME 2 (25 y) - Column, profile; nadir, limb
Contribution of KNMI to Reactive Gases (2) • Near-real-time delivery of ozone data - GOME (SCIAMACHY ?) - OMI (launch 2004, follow-up of TOMS) - High resolution - 13*24 km - Global coverage in 1 day • Minor trace-gas retrievals from UV-Vis - Tropospheric (stratospheric) NO2: Observation operator, detailed error estimates OMI - high resolution
Contribution of KNMI to Reactive Gases (3) • Dutch TM5 CTM with regional zoom capability - Use of ECMWF meteorological fields to drive CTM - Tropospheric and stratospheric chemistry - Chemistry parametrizations (ozone, methane) - Experience with couplers (PRISM project)
The MOZART-2 Chemistry Transport Model • State-of-the-art CTM including 65 chemical species and ~170 reactions • Online version coupled to ECHAM GCM almost ready • Soon full coupling to multi-modal aerosol scheme • „Whole atmosphere“ (0-250 km) version available Martin G. Schultz, MPI Meteorology, HamburgGEMS proposal preparation meeting, Reading, 15-16 Dec 2003
Chemical Weather with MOZART • Script chain in place to perform monthly run almost automatically • Run from April 2000 – September 2003 available • Postprocessing and web interface need to be developed • Validation in progress Martin G.

Issues • Near realtime emission data (in particular biomass burning) • Vertical distribution of assimilated columns • Interference of multi-species column assimilation on chemistry (thus forecasts) • What boundary conditions are required by RegAQ? • Validation? • Consistency between RG and aerosols (to what degree and when?)
