  1. Plenary discussion on modelling

  2. Sep-Nov 2007: Simulation and analysis for year 2004 Suggested emissions: Anthropogenic CO, NOx, NMVOCs, N2O from IIASA Anthropogenic CH4 from Philippe Bousquet Natural CH4 from Philippe Bousquet Biomass burning CH4 from Philippe Bousquet Natural CO, NMVOCs, NOx, N2O: Each model use their current emissions, if N2O not in, use GEIA for N2O. Biomass burning CO, NMVOCs, NOx, N2O: GFED Suggested output: O3, CO, NO, NO2, CH4, N2O monthly average mixing rat OH monthly avg concentration Methane loss (kxOHxCH4) monthly avg molec/cm3s Format: Netcdf Pressure, Temperature, CH4 (mix ratio) 6 hourly fields for each FTIR station. Format ASCII CH4, (NO2, HCHO, CO) vertical column (molec/cm2) could be taken out either at same time as FTIR or ideally at 10:30 local time. Format ? OH daily mean concentration. Format netcdf

  3. Analysis: • CO, CH4: Make comparison with NOAA ESRL surface station network. Responsible Stig Dalsøren. • O3, OH: Compare O3 WDCGG stations. OH, CH4 loss compare models. Responsible Stig Dalsøren. • FTIR comparison: Responsible Michiel van Weele + one from FTIR group. • SCIAMACHY comparison: Responsible Michiel van Weele/Christian Frankenberg. • N2O comparison: Use stations from NITROEUROPE (Philippe Bousquet involved there). Also some stations available at WDCGG. Responsible Philippe Bousquet/Isabelle Pison.

  4. Dec-Jan 2007/08: Sensitivity runs Suggestions: All models: Study with link to ACCENT/IPCC discussed at OH meeting in Mainz. CO and methane emission pulses and effect on GWP/radiative forcing. Each model: Could/should come up with suggestion for one or two more studies here. Could be free to do something they find particular interesting. UiO: Effect on OH and methane of increased emissions in southeast Asia 1980-2020 (ongoing) (Changes in land use and its effect on the oxidation capacity through changed emissions of N2O and NOx) KNMI: Fill in suggestion LSCE: Fill in suggestion

  5. Jan – Feb 2008:Evaluation of sensitivity runs Analysis/Output: ACCENT study, coordinated analysis. Other studies, each model group do their own analysis

  6. Mar-May 2008: Coupling with full set of LPJ routines Do a simulation with the new routines and compare it with the year 2004 simulation. Highlight differences and evaluate the performance of using LPJ routines by comparison with some of the same measurements as in the 2004 run. Is the time frame suggested here possible for LPJ? Which fields could be provided to the ACMs? Format of files…

  7. Jun-Dec 2008: Long run(s) 1980-2007 Time periods: UiO: 2000-2007 ECMWF IFS meteorology KNMI: Fill in LSCE: Fill in Suggested emissions: 1980-1999/2000: Biomass burning and anthropogenic CO, NOx, NMVOCs from RETRO. Biomass burning N2O from RETRO Anthropogenic N2O ? (GEIA has emissions from Bouwman for 1990) Anthropogenic, biomass burning, natural emissions CH4 from Philippe Bousquet Natural emissions: From LPJ. 2000-2007: Anthropogenic CO, NOx, NMVOCs, N2O from IIASA May be problems with overlap and inconsistencies between the two periods. Anthropogenic, biomass burning, natural emissions CH4 from Philippe Bousquet. (Only available until 2005) Biomass burning CO, NOx, NMVOCs, N2O from GFED. Use files with temporal resolution of 8 days. Natural emissions: From LPJ.

  8. Suggested output/analysis: The focus could be on trends and variations in OH, CH4 and O3 over the chosen time period. Comparison with observed time series (from HYMN partners and others) should be performed. Which measurement to compare with? Need to decide the output from the models

  9. Jan-Oct 2009: Future simulation for year 2030 on transition to hydrogen economy UiO only model obliged to do this. Emissions: 2030 scenario for anthropogenic emissions from IIASA. All components except hydrogen. Keep natural and biomass burning emissions at 2004 level or use LPJ if they make future scenario. Hydrogen emissions should be coordinated with EUROHYDROS project. EUROHYDROS has not yet defined future emission scenario and simulations. Output/analysis: Effect on oxidation capacity of transition to hydrogen economy.
