Across Germany

It’s rainy day now that we drive through Germany. The night and morning were pretty cold so it took some time for the CPCs (Condensation Particle Counter) to warm up. CPC optically counts the number of particles in the sample.

There is moderately traffic on the way and quite a many trucks that we were are to chase. Concentrations on the highway are basically from 10000 to 40000 #/cm3 peaking at 400000 to 10 million #/cm3 when driving behind trucks and chasing them uphills.

Now we are having a stop at Göttingen and the sun is slitgly showing up.
