The PARADE campaign will take place at the Taunus Observatory on the summit of the Kleiner Feldberg between the 8^th of August and 9^th of September 2011. There will be a one-week setting up period (CW 32) followed by 4 weeks (CW 33-36) of measurements (until ~ 9^th of September).

The heavily instrumented (see ″instruments″), semi-rural site (see ″conditions″) allows us to examine the effects of both biogenic and anthropogenic emissions on radical chemistry (both day and night) and also on the nucleation, growth, composition and aging of particles.
