SYSTEM DESCRIPTION
The
objective of this European Operational Air Quality Forecasting System is to
provide to the general public and efficient and reliable operational system to predict
the Air Quality at European level.
The
system uses WRF/CHEM (NOAA,US) model to simulate the
atmospheric dispersion process. The system is running with the CBM-Z-MOSAIC
chemical mechanism.
The
CMAQ model is running over a domain with 50 km spatial resolution by using EMEP
polar projection emission inventory and transformed to Lambert Conformal
Conical Projection which is the projection showed in the Internet maps. The
model domain has 109 x 99 x 12 grid cells.
The
Emission processor is the EMIMO V2.0 model (UPM, 2005) which includes the EPER
registry from the Environmental European Agency. The model uses the CLC2000
landuse data for EU25 domain (100 m spatial resolution) and USGS 1 km for the
outside EU25 domain areas. The system uses GTOPO 30’’ for topography. Meteorological
boundary conditions are provided by the daily global GSM forecasts as obtained
from NCEP servers.
The
system is providing hourly, daily maxima and daily average information related
to O3, SO2, NO2, CO, PM10, PM2.5 and NH3 pollutants.
The
system architecture is configured in a way that at about 12:00 p.m. the
simulation should be uploaded on-line in the Internet.
The
system is operating as an experimental product. No guarantee is made for a continuous
service since this tool is provided with the only financial effort of the
Environmental Software and Modelling Group (UPM).
