The hidden cost of using low-resolution concentration data in the estimation of NH3 dry deposition fluxes

Long-term monitoring stations for atmospheric pollutants are often equipped with low-resolution concentration samplers. In this study, we analyse the errors associated with using monthly average ammonia concentrations as input variables for bidirectional biosphere-atmosphere exchange models, which are commonly used to estimate dry deposition...

Non-stomatal exchange in ammonia dry deposition models: comparison of two state-of-the-art approaches

Abstract. The accurate representation of bidirectional ammonia (NH3/ biosphere–atmosphere exchange is an important part of modern air quality models. However, the cuticular(or external leaf surface) pathway, as well as other non-stomatal ecosystem surfaces, still pose a major challenge to translating our knowledge into models. Dynamic...
