EURAD is financially supported by the BMBF within the Atmospheric Research programme (AFO2000). Long-term applications with respect to EU directives have been supported by the Environmental agency of North-Rhine-Westphalia (LUA).
Emission data have been provided by EMEP and TNO/UBA. The landuse data have been provided by IFU, Garmisch-Partenkirchen. Access to meteorological data (ECMWF) have been given by the meteorological department of the IGM, University of Cologne. The measurements are provided by the Environmental agency of North Rhine-Westphalia.
Numerical calculations have been supported by the RRZK, University of Cologne and the Research Center Juelich (ZAM, NIC, ICG-II).
We gratefully acknowledge the very helpfull discussions with the colleagues from the Environmental Agency of North-Rhine-Westphalia (LUA), the German Environmental Agency (UBA), the EUROTRAC community (in particular GLOREAM and TOR), the Ford Research Center and the ICG-II of the Research Center Juelich.
