Presentation Transcript

  1. Comparison of UTOPIHAN 2 Observations with MATCH-MPIC Results M. G. Lawrence Max Planck Institute for Chemistry Mainz, 16.2.2004

  2. The Chemical Weather Forecast System • MATCH-MPIC • Model of Atmospheric Transport and Chemistry • NMHC Chemistry (up to C5 HCs) • 56 Species, 140 Reactions • 21 CO Tracers • Online wet & dry dep, j-vals, emissions • Meteorology: NCEP GFS (T42-L42) • Full tropospheric hydrological cycle • Diagnosed Clouds, Convection • Near real time (NRT) run • 3-day Forecasts (completed ~ 6 UTC)

  3. New

  4. Flights through model output, on FTP server, in approx. NASA-Ames format (version 2 => rerun)

  5. CO and Regional CO Tracers (flight-by-flight)

  6. SCIAMACHY OVERPASSES FOR 14-16 JULY IN VALIDATION SET(=> special attention to quality of retrievals)!

  7. Substantial enhancement in • UT CO (~20-30 ppbv • more than on 15.7) • Model attributes this to • Western Europe • Outflow not deep enough • Model underestimates • observations everywhere

  8. x x x x

  9. Time series not very meaningful on this scale for a global model… x

  10. UTOPIHAN CONTRACE Modeled peak convective outflow not deep enough, too diluted

  11. Bulk Konvektionsparameterisierungen Plume Ensemble Fits well with theoretical work (in progress)

  12. Einfluss auf bodennahe Schadstoffkonzentrationen CONTRACE Beobachtungenund MATCH-MPIC Vergleich

  13. PTRMS Comparisons (O3, Propane, etc. still to be done)

  14. Regular high Isoprene levels: Substantial underestimate of the Influence of European Deep Conv? Much longer UT Isoprene lifetime? Other coinciding masses?

  15. Theoretical work on deep convective transport

  16. Bulk Konvektionsparameterisierungen Plume Ensemble

  17. Tracers in MATCH-MPIC: Zonalmittel für Juli 2001  = 1 d  = 2 d

  18. Extras
