Topics for MPI-C Collaborations with the COPS-TRACKS Initiative

Mark Lawrence, Marc Salzmann, Horst Fischer

• Cloud Resolving Chemistry-Transport Modelling– WRF (Weather Research and Forecast Model)– Full gas-phase tropospheric chemistry implemented– Regions: Maritime (TOGA COARE) and

Continental (ARM, STERAO)– Studies ( SFB 641 – The Tropospheric Ice Phase):

• Convective tracer transport• Scavenging (especially by ice), Retention coefficient• Lightning NOx production

• MPI-C Field Campaigns: Tropospheric Chemistry Over Europe

Tropospheric Chemistry Over Europe

• HOx Budget

• Long Range Transport (Import and Export)• Vertical Transport (Deep Convection)• Latitudinal Gradients of Trace Gases• Seasonal Variations
