General information and objectives

Objectives:
• Determine and model ozone concentration trends
• Measure ozone concentrations over Europe and to study seasonal, latitudinal and vertical variations.
• Measure any transfer of ozone between the boundary layer and the free troposphere, and between the troposphere and the stratosphere.

Highlights of TOR current scientific results
One major contribution by the TOR project is the establishment of nearly 30 stations throughout Europe, equipped with highly sophisticated instrumentation to study the formation, transport and distribution of ozone in the troposphere.
Ozone levels in the troposphere are increasing. Measurements at Mace Head (Ireland) show an average ozone increase of 1.4 ppb per year in the clean air on the western edge of Europe; a similar increase has been observed in the free troposphere from measurements on the Zugspitze (Germany)at 300 m.
Analysis of the historical records since the beginning of the century at Pic du Midi (France) shows that there has been roughly a three-fold increase in ozone, and the rate of increase itself is increasing markedly.
These increases can only be attributed to man's activities and ma have far-reaching effects on health and climate in the future.
