! Summary We can provide data for both EMEP-Intensive campaigns for DIGITEL High Volume Sampler (daily means, PM1, PM2.5 and PM10) MAAP, Multi Angel Absorption Photometer (Model 5012) (Minute means) Berner, 5-stage-BERNER-type-impactor (mass, water soluble ions, organic and elemental carbon, OC, EC) (daily means for selected days,13 during summer and 15 during winter campaign) GRIMM Type ESVC 265, optical detection of PM1, PM2.5 and PM10 (half-hourly means) TDMPS TDMPS (twin-differential-mobility-particle-sizer) with APS (aerodynamic-particle-sizer) in combination with a thermo-denuder (10 minute means and daily contour plots) TOF-AMS, Particle-Mass-Spectrometer (data in winter campaign available) Especially the time slot of the winter campaign shows only situations with westerly winds and the Winter 2006/2007 was in Germany extremely mild. The comparison of both campaigns therefore give very untypical results for the Melpitz site. They are differ from that of long-time observations. !

Particulate Matter reasons We acknowledge the support from the Umweltbundesamt in Germany (projects 351 01 022 and 351 01 031) and continuation of measurements in 2006/07 (project 351 01 38) We would like to thank Jörn Hanß, Eveline Neumann, Annelie Thomas, Helga Mamczak, Brigitte Gerlach and Anett Kappe. actions
