"Quiz Box "

Learning is an iterative process.
So, if you are not sure about your answer, dont hesitate to visit the info boxes or plates using the following shortcuts:

• Aircraft NO_x
      

   

• Aircraft Ozone
      

   

• Road Traffic NO_x
      

   

• Road Traffic Ozone
      

   

Vocabulary:

• UTLS

   

• pptv

   

• NH / SH

   

• PBL

   

• Emission

   

• Loss rate

   

Please try to answer the following questions

• Is there a dependency between NO_x and ozone air pollution?

   

• Can you explain roughly what NO_x emissions effect in the air?

   

• . . . and in the model?

   

• Look at the station records of "aircraft ozone":
  Why is there a significant concentration in Mainz at ground level whereas no plane exhausts any NO_x right there?

   

• Assuming all trafic was stopped whithin one moment:
  What would happen to "traffic ozone" production?

   

• What is the major ozone source in the upper troposphere?

   

• Why was Road Traffic NO_x distribution only simulated over 13 months?

   

• What is called "summer smog"?

   

• Which simplification does this model distribution not allow to simulate "summer smog"?

   

• Why / how does the PBL "breath"?

   

• What causes the "breathing" of the hemispheric air volume?

   

• And finally: How would you describe the role and defend the inalienability of numerical models in (atmospheric) science - despite inherent lacks and shortcomings?
