Ulrich Platt and Ulrich Schurath |
Monday, 2. 8.: Introduction (overview, program of the summer
school) (Ulrich Platt)

Static structure of the atmosphere
-
The different ``floors of the atmosphere'' (troposphere, stratosphere,
...)

Fronts, barotrope/barocline layering
Afternoon: Atmospheric aerosols I : (Ulrich Schurath)
-
The planetary boundary layer
-
Atmospheric aerosols: sources, classification by composition, by size

Water in the atmosphere
-
Cloud nucleation: Kelvin effect and Koehler theory

Deliquescence, efflorescence
Tuesday, 3. 8.: Dynamics of the atmosphere (Ulrich Platt)

Transport and mixing processes in
the environment: Diffusion -Advection, Eulerian and Lagrangian pictures

Particular solutions (geostrophic
wind, Ekman Spiral ...)

- Measurement techniques
Wednesday, 4. 8.: Basis of atmospheric chemistry (Ulrich
Schurath)

Special cases (SW: no Planck term,
LW: no scattering, etc.)
-
Radiation in clouds (path length distribution,
``anomalous'' cloud heating)

greenhouse effect
