2. Motivation Health effects caused by the smog
Smog was in the public gaze in August
If we want to forecast something, we need to understand the phenomenon
Figure 1. The synoptic situation at 21 August 00UTC over Europe

3. Data Surface observations: Wind parameters
Rain location and intensity; precipitation rate
Temperature
Doppler lidar
SODAR
RASS and ceilometer?
Regular observations from Finland, Russia and Estonia
YTV and FMI concentration observations

4. Figure 2. A 24-h period of ceilometer echo intensity observations at Vallila, Helsinki, 21 August The height of the MHs determined by the ceilometer and radiosoundings (Richardson number method) are superimposed on the ceilometer raw echo data.

5. Things to learn: How useful are the Testbed observations?
Can we use the Testbed data in long or regional range pollution transport (e.g. smog) episodes?
How to use Testbed data better?
Better understanding in mesometeorology
