Modelling domains

Modelling domains (I) Updated emission data outside Lombardy are currently lacking (INEMAR2005). Focus has partly been shifted to the Lombardy domain (finer grid resolution) Availability and consistency of regional measures at the scale of the entire Po-valley scale is difficult to achieve. The number of scenarios identified by the Lombardy Region as potentially interesting is larger than originally expected. Ref. Technical annex

Emission scenarios

Emission scenarios (I) Lombardy focus: Due to data unavailability from most Regions, focus has shifted from Po-Valley to Lombardy implying a different balance in the number of planned scenarios over the two domains. Difficulty of building air quality plans at the scale of the whole Po-valley. Priority scenarios: Apart from the 2005 BC, a few 2012 scenarios have been identified as priorities and should possibly be run by a maximum number of models. Sensitivity scenarios: To be run by minimum number of models. Some will require increased work load. Comparison consistency: Same model should be used across scales or across scenarios to reduce pre-processing work and facilitate comparison. Non-contract participants: Welcome to contribute to any scenarios.

Boundary conditions

Boundary conditions (I) All models do generate their own BC from Po-Valley to Lombardy domains. No data transfer needed EMEP and CHIMERE Europe BC should be interpolated on a 30 km UTM output grid (Po-Valley domain + 1 grid cell?) on all original model vertical levels. Data to be sent to JRC (JRC script) Species list: O3, NO, NO2, SO2, NH3, PM2.5, PM10, SULF, NITR, AMMO, BC, ORG Frequency: 1h or 3h? Daily for PM? Transfer from CHIMERE to EMEP for BC sensitivity simulation (through JRC or direct?)
