FACE (Feldberg Aerosol Characterization Experiment)

View by the aerosol inlets to the "Grosser Feldberg". Picture: MPIC

Two field projects (FACE2004 & FACE2005) performed at the Taunus Observatory (TO) of the Goethe University Frankfurt on the "Kleiner Feldberg", Germany.

Objectives:
Instrumental tests & comparisons, CCN activation studies, air mass characterization in the vicinity of the polluted Rhein-Main area, nucleation events.

In 2011 and 2012 we returned to the Feldberg for the experiments "PARADE" and "INUIT-TO".


Instruments:
Q-AMS, C-ToF-AMS, SPLAT, various particle counters (CPC, OPC), SMPS etc.

People involved:
F. Drewnick, J. Schneider, J. Curtius, M. Kamphus, H.-J. Vössing, S. Walter, M. Ettner-Mahl, A. Kürten, R. Weigel, S. Zorn, S. Hings, B. Winterholler

Cooperation with:
Biogeochemistry Dept., MPIC Mainz (U. Dusek, G. Frank, D. Chand)
University Mainz (L. Schütz)
University Giessen (K.-P. Hinz)
University Frankfurt (H. Bingemer)
