Summary:

VOTALP is a EU research project started in April 1996. The four major questions of VOTALP are:

• What is the contribution of stratospheric intrusions to Alpine ozone concentrations?
• How important is the advection of polluted air towards the Alps, for instance during foehn, and how is the air brought down into the valleys?
• How important is the in-situ production of photooxidants in Alpine valleys?
• What is the effect of exchange processes between the valley atmosphere and the free troposphere on the ozone concentrations in the valleys and in the free troposphere?

VOTALP combines measurements with model simulations to provide answers to these questions.

The follow-up project VOTALP-2 is being carried out in the period April 1998 - March 2000.
