What has been done?

• Simulations with LOTOS (30x30 km2)
• Scenarios 1 - 5 as defined on EURODELTA webpage
• Output for coarse grid of selected species and
  deposition totals for delivery to JRC
• Output of all species in all layers on sub-grids
  for use as boundary condition in CD II
• A first validation
• Submission of results of the base case for use in
  the model inter-comparison in the framework of
  the EMEP Unified-model review. (Coordinated by
  TNO-MEP, M. van Loon. To be presented nov 3-5,
  Oslo, TFFM )
• First analysis of the LOTOS results for the base
  case for key species, using
• AIRBASE and EMEP observational data
• Using additional data from various sources

4
First results. Ozone correlation coefficients
5
First Results. Ozone daily maximum
6
First results, PM10

• Note that model output for PM10 does not include
• Sea-salt
• Wind blown dust
• Biogenic Secondary Organic Aerosols (BSOA)
• Resuspension from road dust
• It does include
• Secondary Inorganic Aerosols
• Primary aerosols (using the CEPMEIP emissions
  database)

First results. PM10 yearly averages
Underestimation similar to EMEP model (see status
report 1/2003, part II)
8
IntermezzoObserved-Modelled (EMEP) versus
Observed with observations from AIRBASE (2000).

First results SO4 (daily mean)
Correlations around 0.5
