Dry deposition velocities [PDF]

, 1984
Dry deposition velocities are very difficult to predict accurately. In this article, reported values of dry deposition velocities are summarized. This summary includes values from the literature on field measurements of gas and particle dry deposition velocities, and the uncertainties inherent in extrapolating field results to predict dry deposition ...

Nitrogen and sulfur deposition on regional and global scales : a multimodel evaluation [PDF]

, 2006
[1] We use 23 atmospheric chemistry transport models to calculate current and future (2030) deposition of reactive nitrogen (NOy, NHx) and sulfate (SOx) to land and ocean surfaces.

Improving Wet and Dry Deposition of Aerosols in WRF‐Chem: Updates to Below‐Cloud Scavenging and Coarse‐Particle Dry Deposition

Journal of Advances in Modeling Earth Systems, 2022
Wet and dry depositions of aerosols in WRF‐Chem are revisited and updated based on recent observational findings. Traditionally, in‐cloud scavenging was thought to play a more dominant role in aerosol wet removal than below‐cloud scavenging.

Dry Deposition of Atmospheric Nanoparticles

, 2021
The increasing number of pollutants emitted or released during and after the industrial revolutions caused major changes that were harmful to the environment and the health of the population. The harms resulting from air pollution were evident in the most industrialized regions, due to the large amount of pollutants emitted in these regions ...

High NH3 deposition in the environs of a commercial fattening pig farm in central south China

Environmental Research Letters, 2021
Intensive livestock production has been increasing, and has resulted in the emission of more than seven teragram per year of ammonia (NH _3 ) in China in recent years.

Precipitation trend increases the contribution of dry reduced nitrogen deposition

npj Climate and Atmospheric Science, 2023
Given the leveling off in oxidized nitrogen emissions around the world, the atmospheric deposition of reduced nitrogen (NH x  = NH3 + NH4 +) has become progressively critical, especially dry deposition, which presents great threats to plant growth.

Particle Deposition in Drying Porous Media [PDF]

Materials, 2021
The drying of porous media is a ubiquitous phenomenon in soils and building materials. The fluid often contains suspended particles. Particle deposition may modify significantly the final material, as it could be pollutants or clogging the pores, decreasing the porosity, such as in salt, in which particles and drying kinetics are coupled. Here, we used

The impact of drought on total ozone flux in a mountain Norway spruce forest

Journal of Forest Science, 2020
In order to understand the impact of summer drought on dry deposition of tropospheric ozone (O3), we compared severe and mild drought periods of summer 2018 in a mountain Norway spruce forest at Bílý Kříž, Beskydy Mts.

Prediction of the Deposition of Dry Powder Aerosols [PDF]

The AAPS Journal, 2009
The trajectory, mass fluxes, and deposition of aerosolized particles in a complex tubular system have been predicted. A procedure based on Lagrangian stochastic modeling is proposed to enable the anticipation of such phenomena, taking advantage of experimental results to characterize the air flow.
