Abstract
Ozone (O3) is formed in the troposphere via a complex chemical reaction scheme involving nitrogen oxides (NOx), volatile organic carbons (VOCs), and solar radiation. The reactions of (O3) with (NOx) and sunlight are fast; the net production of (O3), which involves VOCs, is considerably slower. The differing reaction times lead to varying transport distances in both horizontal and vertical directions within the troposphere. Therefore, the interplay of chemistry with atmospheric transport (meteorology) makes the dynamics of ozone a challenge in teaching atmospheric chemistry. This contribution shows a pedagogical concept of how to study the issue in a graduate students' study project. The students learn how to set up and operate an air chemistry monitoring site, process raw data, conduct data quality assurance, and interpret the data in terms of the production of (O3). Additional educational goals were to responsibly make decisions during field work, learn efficient teamwork, and disseminate the key results to the public. A quantitative pedagogical evaluation on the basis of students' anonymous responses is given.
