Apparatus for Dry Deposition of Aerosols on Snow [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Abstract. Deposition of light absorbing aerosol on snow can drastically change the albedo of the snow surface and the energy balance of the snowpack. To study these important effects experimentally and to compare with theory, it is desirable to have an apparatus for such deposition experiments.

Estimation of atmospheric nutrient inputs to the Atlantic Ocean from 50 degrees North to 50 degrees South based on large-scale field sampling: Fixed nitrogen and dry deposition of phosphorus [PDF]

open access: yes, 2010
Atmospheric nitrogen inputs to the ocean are estimated to have increased by up to a factor of three as a result of increased anthropogenic emissions over the last 150 years, with further increases expected in the short- to mid-term at least.

Experimental study on aerosol dry deposition characteristics in wind tunnel simulation [PDF]

open access: yesE3S Web of Conferences, 2022
The radioactive aerosols are produced during the operation of nuclear power plants will cause certain harm to human body. Dry deposition is one of the important factors affecting the aerosols deposition to the ground, and radioactive aerosols and common ...

Chemical signature of Saharan dust on dry and wet atmospheric deposition in the south-western Mediterranean region [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2013
We studied if the presence of Saharan dust intrusions and the rains modify the chemical signature of the wet and dry deposition in the southern Iberian Peninsula.

Atmospheric Deposition of Benzo[a]pyrene: Developing a Spatial Pattern at a National Scale

open access: yesAtmosphere, 2022
Benzo[a]pyrene (BaP), an indicator of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere, is an important ambient air pollutant with significant human health and environmental effects.

Deposition velocity of H2: a new algorithm for its dependence on soil moisture and temperature [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2013
We derive an analytical expression for the deposition velocity of H2 on soil, vd, which explicitly describes the dependence of vd on the average soil moisture, and temperature, T.

The importance of biomass net uptake for a trace metal budget in a forest stand in north-eastern France [PDF]

open access: yes, 2010
The trace metal (TM: Cd, Cu, Ni, Pb and Zn) budget (stocks and annual fluxes) was evaluated in a forest stand (silver fir, Abies alba Miller) in north-eastern France.

An overview of atmospheric deposition chemistry over the Alps: present status and long-term trends [PDF]

open access: yes, 2006
Several research programs monitoring atmospheric deposition have been launched in the Alpine countries in the last few decades. This paper uses data from previous and ongoing projects to: (i) investigate geographical variability in wet deposition ...

A Study on Dust Dry Deposition: Wind-tunnel Experiment and Improved Parameterization [PDF]

open access: yes, 2013
Dust deposition is a key component of the dust cycle in the Earth system. The lack of understanding for the mechanisms of dust deposition has been a major bottle neck to the development of the dust-related research field.

Evaluation of deposition fluxes in two mountain Norway spruce stands with different densities using the extended Canopy Budget Model

open access: yesJournal of Forest Science, 2013
The field study in a mountain forest at Bílý Kříž provides a comparison of element fluxes for two adjacent forest spruce stands of the same age (29 years in 2005) but with different stem densities.
