Short summary
Short summary
Vegetation removes tropospheric ozone through stomatal uptake, and accurately modeling the stomatal uptake of ozone is important for modeling dry deposition and air quality. We evaluated the stomatal component of ozone dry deposition modeled by atmospheric chemistry models at six sites. We find that models and observation-based estimates agree at times during the growing season at all sites, but some models overestimated the stomatal component during the dry summers at a seasonally dry site.

Short summary
Short summary
A primary sink of air pollutants is dry deposition. Dry deposition estimates differ across the models used to simulate atmospheric chemistry. Here, we introduce an effort to examine dry deposition schemes from atmospheric chemistry models. We provide our approach’s rationale, document the schemes, and describe datasets used to drive and evaluate the schemes. We also launch the analysis of results by evaluating against observations and identifying the processes leading to model–model differences.

Short summary
We considered it important to complete the content knowledge of secondary school physics with those concerning atmospheric humidity, fog, and air pollution. For this aim, a three-hour teaching module was elaborated, which included the analysis of the air-polluting events together with the foggy weather. The experimental curriculum motivated the students to understand processes that take place in their environment regarding environmental protection.

Short summary
Agricultural fertilizers can release ammonia into the air, reducing fertilizer efficiency and affecting air quality. We measured ammonia exchange between soil, plants and the atmosphere in a crop field after fertilizer application. Emissions were stronger during the day and weaker at night. Total nitrogen loss was about four percent of the applied fertilizer.
