  1. Solène Turquety – GEOS-CHEM Meeting April 4, 2005 GEOS-CHEM Near-Real Time Full-Chemistry SimulationsS. Turquety, D. J. Jacob, R. M. Yantosca, R. C. Hudman, L. Jaeglé, S. Wu • Objectives : • ICARTT campaign summer 2004: • Support flight planning: monitor any large deviations between the aircraft observations and our understanding of ozone and aerosol processes that may cause alteration of flight plans, • Generate a set of preliminary findings • Support satellite validation: Used at JPL by Qinbin Li for first analysis of TES and MLS data • Comparison with in situ measurements: Used byDan Jaffe’s group in University Washington • More?....

  2. GEOS-CHEM NRT full-chemistry simulations MODIS hotspots: assume 100ha/hotspot Emissions/ unit area (Yevich and Logan) Vertical distribution Fok-Yan Leung Emissions (Molec/cm2/s) 6km x 60 % 3km 40 % PBL INTEX-NA Flight tracks 1/07-15/08 Solène Turquety – GEOS-CHEM Meeting April 4, 2005 • Daily full chemistry simulations v6-02-03 : • 2x2.5 horizontal resolution, 30 levels, global • based on GEOS-4 1st look met fields • daily-updated biomass burning emissions for North America based on MODIS hotspots • daily plane flight diagnostic • (1st included for ICARTT) • 2-D “column” timeseries for tropospheric CO, O3, NO2, HCHO for 1st look, direct comparison with satellites • Runs semi-automated using perl scripts developed by Bob Yantosca

  3. GEOS-CHEM NRT full-chemistry simulations 0.00 2.5 8.3 tons CO / ha burned 0.00 Solène Turquety – GEOS-CHEM Meeting April 4, 2005 • Future improvements: • New version of GEOS-CHEM (v7) • Cf. presentation R. M. Yantosca • NEI 1999 for North American anthropogenic emissions (now in standard version of the code) • Cf. presentation R. Hudman • Improve parameterization of lightning • (adapt it to GEOS-4) • Cf. presentation R. Hudman • Improve biomass burning emissions (emissions / unit area) • Other ??? Including peat burning

  4. GEOS-CHEM NRT full-chemistry simulations Solène Turquety – GEOS-CHEM Meeting April 4, 2005 • NRT == available with delay of ~ 2-3 days • Output data archived for 1 month at Harvard • (ICARTT period July-August 2004, and September 2004 still available): • /as2/priv/ICARTT/ • Daily means all GEOS-CHEM tracers, met. data, sources… • 3h timeseries 3D: • CO, O3, NOx, PAN, PMN, HNO3, ACET, sulfate, AOD • 3h timeseries 2D: • tropospheric columns CO, O3, HCHO, NO2 • Along flighttrack for ICARTT when specified: • all GEOS–CHEM chemical tracers • absolute humidity • Temperature • wind speed • NO, OH, HO2 • JNO2, JO1D • Aerosol optical depths • O3 P/L rates • Restart files
