Article Synopsis
- * A study conducted in Paris quantified these effects using a model that included tree-specific attributes and air-quality simulations from June to July 2022.
- * Results indicated that while the aerodynamic effect of trees increased pollutant concentrations in high-traffic areas, the dry deposition effect was minimal, and biogenic emissions significantly raised concentrations of certain compounds, suggesting a preference for planting low-emission trees.
The presence of a weekly cycle in the abundance of an atmospheric constituent is a typical fingerprint for the anthropogenic nature of its emission sources. However, while ammonia is mainly emitted as a consequence of human activities, a weekly cycle has never been detected in its abundances at large scale. We expose here for the first time the presence of a weekend effect in the NH total columns measured by the IASI satellite sounder over the main agricultural source regions in Europe: northwestern Europe (Belgium-the Netherlands-northwest Germany), the Po Valley, Brittany, and, to a lesser extent, the Ebro Valley.
