pTOMCAT
  • Sulphur chemistry + heterogeneous chemistry.
  • End of June: new calculator.
  • New emission code.
slide3
1year spin-up + 1year simulation T21old machine (2002-2003):

Time-pos calculations

All transp. modes

Road -5%

Ship -5%

8months new machine (2002):

All transp. Modes

Aircraft -5%

Done
  • Problems with O3-production tracers.
  • Diagnostics
  • Forgotten O3 production rates in ncdf-files.
  • Not extracted the deposition rates.
transport mode 5
Transport mode -5%:
  • Road -5% at the surface:
    • NOx: -2.5 % EU / -1.5 % US
    • Ozone: -0.6 % EU /-0.3 % US
      • but +0.05 % EU in January
  • Shipping -5% at the surface:
    • NOx: -4.0 % sea / -0.5 % North Sea
    • Ozone: -.5 % South H. / -.25 % North H.
aircraft 5
Aircraft -5%:

NOx: -2% max emission area

Ozone: -2% (-0.3 ppbv)
