  1. Modelling exercise on scale dependencies M. Schaap, L. Rouill, A. van Pul, A. Graff, H. Fagerli

  2. M. Schaap Fossil Fuel pilot Introduction • Model exercise to: • Assess model performance of CTMs as function of model resolution • Assess robustness of citydelta approach used in EC4MACS

  3. M. Schaap Fossil Fuel pilot Proposed simulations at four resolution LON x LAT ~ Resolution 1.0 x 0.5 ~ 56 Km 0.5 x 0.25 ~ 28 Km 0.25 x 0.125 ~ 14 Km 0.125 x 0.0625 ~ 7 Km

  4. M. Schaap Fossil Fuel pilot Annual model simulations with: • Model choice • Meteorology for 2009 • Land use • Natural emissions, etc • Fixed: • EC4MACS emission totals (modification of TNO-MACC) • INERIS SNAP 2 emission time profile module • EURODELTA time profiles • Emission heights prescribed • EC4MACS domain • Output in netcdf files

  5. M. Schaap Fossil Fuel pilot Time line – fast! • May 1 Protocol ready and published • May 10 Input data made available • June 1 Delivery for 0.5x0.25 data to INERIS • June 10 First response on quality control • July 15 All simulations delivered to INERIS • Sept 1 Scale dependent model performance evaluation ready • Sept X Presentation at EMEP SB • Oct 15 EC4MACS city delta scaling factor results analysed

  6. M. Schaap Fossil Fuel pilot Output • EMEP note on scale dependency • EC4MACS chapter on robustness and uncertainties
