Report Quantify Act. 3 meeting in Oslo 27 June 2005

Peter van Velthoven – 25 August 2005

 

Present: O. Dessens (UCAM), S. Dalsoren (UiO), V. Grewe (DLR), P. Hoor (MPI-Chem), I. Isaksen (UiO), P. Jockel (MPI-Chem), M. Prather (UCI), C. Schadt (ETH), P. van Velthoven (KNMI)

Absent due to family circumstances: D. Hauglustaine (CNRS, LPCE)

 

Most groups gave a presentation about the current status of their models. All models seem ready for the preliminary simulations of the current/future impact of the transport sector. Subsequently we discussed the workpackages with deliverables (see bottom) in year 1 of Quantify.

 

WP 3.1.1 Model evaluation

 

Set-up

 

The year 2003 has been selected for the model evaluation. Campaign data to be used include SPURT, UTOPIHAN-Act, MOZAIC, CONRACE, VINTERSOL?, INTEX?.  These will be included in the ETH-MEG database with priority.

Furthermore Sciamachy NO2-columns (perhaps also HCHO) for 2003 will be compared.

Models will be run in the same set-up as for the current impact study (see below).

 

Diagnostics/analysis:

-         Include a radon tracer (boundary layer, convective transport)

-         Include a CH3I tracer (marine boundary layer) Michael Prather will provide details about how to do this.

-         Use Brunners output routine for the tropopause (to be provided by C. Schnadt)

-         ETH will provide time-position files (where models should output their data) as well as the tropopause output routine

-         Output to be provided through ftp to ETH

-         Analysis will be done using the tools for curtain plots (STE), time series and scatter plots/Taylor diagrams

-         Evaluation of boundary venting by analyzing the vertical tracer profiles, rather than the boundary layer height

-         Evaluation of convective transport using the 2003 campaign data, e.g. CONTRACE. It was decided not to use the STEP 1987 Darwin aircraft radon measurements as this is a very limited data set.

 

Model descriptions.

 

Starting from the model inventory made during the EU-Retro project a list of model characteristics required for interpretation of the evaluation runs will be compiled by Schnadt. A questionnaire will be distributed.

 

WP. 3.1.2 Current impact

 

Set-up

Involves 4 model simulations for 2003:

  1. All emissions
  2. Shipping swithched off
  3. Road traffic switched off
  4. Aviation switched off

 

Emissions

It was decided to use the EDGAR emissions, rather than the POET/RETRO emissions because the latter does not yet publicly provide separate emissions data sets for the  transport sectors. 

In case Activity does not timely provide emissions for the transport sectors we will use:

-         road traffic – DLR emissions (to be provided through Volker Grewe)

-         air traffic – AERO2k (Cambridge will contact Chris Ayer at Qinetiq)

An alternative would be DLR1992.

-         Shipping – Endresen (to be provided by UiO)

 

Lightning emission: 5 Tg.

CH4 emissions will be prescribed at the surface.

 

Output

Monthly means on a regular grid, preferably 2.5x2.5 degrees x 1 km

Tracers: O3, NOx, SO2, H2SO4, CH4, OH, aerosols ?

 

 

WP. 3.3.1: Future impact

 

The IPCC A2, B2 scenarios are not suitable for studies of the transport sector. Therefore it will be attempted to use the IASA-2030 emissions scaled to 2050. Ivar will contact Frank Dentener to obtain separate emissions sets for the transport sectors.

 

Actions:

  1. Provide road traffic emissions from DLR (Grewe, deadline: September 2005)
  2. Contact Qinetiq for Aero2K emissions (Dessens, deadline: September 2005)
  3. Contact Dentener about separation of transport sectors in IASA emission scenarios (Isaksen, deadline September 2005)
  4. Provide draft set-up for current impact simulations (Hoor, Jockel- MPIChem, deadline August 2005)
  5. Model descriptions/ questionaire (Schnadt, deadline October 2005)
  6. Provide output routines (Schnadt, deadline : September 2005)
  7. Provide time-pos files (Schnadt, deadline February 2006, possibly earlier)
  8. Provide Endresen’s ship emissions (Gauss, deadline September 2005)
  9. Provide details of CH3I simulation (Prather, deadline September 2005)
