  2. Activity 3: Large scale chemistry effectsWorkpackages • 3.1 Evaluation and current impact • 3.1.1 Evaluation of multi-model performance against observations • 3.1.2 Current chemical composition change by transport emissions • 3.1.3 Effective emissions • 3.1 Key process studies and model improvements • 3.2.1 Precipitation impact on sulphur and nitrogen compounds • 3.2.2 Aircraft induced sulphur impact on UTLS ozone • 3.2.3 Impact of cirrus clouds • 3.3 Future impact and mitigation options • 3.3.1 Future chemical composition change by transport emissions • 3.3.2 Impact of future climate change • 3.3.3 Possible mitigation strategies

  3. Activity 3: Large scale chemistry effectsA1 workshop: ship emissions • Update of DNV ship emissions available on A1 website • Base year 2000 (from 2004 ship info:reduction of 9% - proportional to energy use) • Extended ship type matrix (15 types X 7 sizes) • Includes fishing vessels • Extended and adjusted emission factors • Merged COADS-AMVER for movements • Fuel: 187.2 mton at sea, 9.9 mton in port • To be compared to IEA estimates 170-180 mton fuel, but Russia (16mton) and Panama (1 mton) missing  also about 200 mton • Military ships not included

  4. Activity 3: Large scale chemistry effectsA1 workshop : aviation emissions– FAST2000 • Uses 1990 & 2000 scheduled traffic (OAG tables) – previous inventories used 1991-1992 data • 16 43 representative types • Statistical altitudes profiles from analysis AERO2K – but resulting vertical distribution at cruise level is different … • Z = 610 m • Good agreement in total numbers with other inventories • Military aviation not included – use AERO2K

  5. Activity 3: Large scale chemistry effectsA1 workshop: road transport emissions • More difficult to get good estimates of total fuel use than for aviation and shipping. Many statistics are missing or wrong. • Use EDGAR for the initial A3 runs

  6. Activity 3: Large scale chemistry effectsMethyliodide – a tracer for the marine BL • Perform similar experiment as GMI • e-folding lifetime of 5 days • Intended use: marine LB venting, marine convective transport • Some observations are available from aircraft experiments, Bell et., JGR, 2002. • Emissions • (analysed by Ernst Meijer) • Surface emission only over oceans – provided by S. Strahan • 4x5 degrees, monthly time resolution • Emission units have been converted from kg/s to kg/(m2s) • A few negative values in the emission field have been corrected

  7. Activity 3: Large scale chemistry effectsDiagnostics • Obligatory output is underlined, other output is auxiliary • Tracers • Stratospheric ozone tracer (relative to thermal TP-Brunner) • Troposphere tracers (United States, EU-30, Asia) • Land & ocean tracers, lifetimes 1 day, 10 days, 1/12 year • 3 14CO tracers • Diagnostic experiments • Road traffic, ships, aviation switched off • Lightning 2 Tg + best model estimate - 1 additional run ! • Additional output parameters • Pressure, Net ozone production (3D) • Thermal (Brunner) &dynamical tropopause (2 and 3.5 PVU) (time-pos-files +2-D) • Monthly mean updraft mass fluxes + #events • Columns NO2, HCHO?, ozone (local satellite time, weighted) (2-D) • Wet deposition parameters – 3D+time-pos HNO3 removal (WP3.2.1 participants, tbd by Meijer) • CO and O3 profiles + 2 PVU TP at time-pos • SO2? and NO//NOy/HNO3 • Diagnostic plots • Ozone/CO + CO profiles relative to 2 PVU TP • 24 hr average +stdev profiles of ozone at sonde stations and CO and O3 at CMDL stations

  8. Activity 3: Large scale chemistry effectsAnalysis of output- who does what • Current effects (Hoor, Jockel) • Future effects (Dalsoren) • Model-observations evaluation • Campaigns (Schnadt, Hoor) • Ozonesondes (Schnadt) • Surface observations (Schnadt) • Model-model intercomparison • Land-ocean tracers + updrafts (Schnadt – delegating?) • Ozone tracers [EU, US, Asia, stratosphere] (Grewe) • STE, Ozone/CO (Hoor, Schnadt) • Wet deposition, updrafts (Meijer) • Lightning sensitivity (Meijer)

  9. Activity 3: Large scale chemistry effectsOpen points, Action list • Format of 3D-files (attributes, names, order) (Gauss, PvV) • Interpolation from model levels to altitude + to T42 for climate modellers? (PvV) • Action list (preliminary) • What aerosols will be simulated (PvV contacts Berglen, UiO) • HCHO weighting functions, O3 (PvV contacts Buchwitz, Bremen) • Time schedule (PvV contacts Sausen) • 30 November: • Send netcdf grid definition to Jockel fo emission interpolation (anyone who likes to) • 14 CO definition +emission data(Jockel) • Aero2K 1x1 degree (Dessens) • (Password on) MPI-site for emission data sets (Jockel) • One user/password & sufficeint disk space on ACCENT site (Gauss) • Model description form (everyone – send to Schnadt cc PvV) • Check soot emissions for road traffic (Grewe) • Get new Quantify ship and aviation emissions (PvV) • BB-emission time variation (Meijer) • SO2, Noy time-pos ? (Schnadt) • Netcdf format ok for climate modellers? (PvV) • End December • Monthly mean multi-year isoprene, soil NOx emissions (Jockel) • Time-pos data 2003 (Schnadt) • Description of wet dep schemes (Meijer) • 1 January – runs should start • Autumn 2006 • SSTs for 2000 and 2050, as a climatology from ECHAM5/OM FAR (Grewe)
