The portion of total atmospheric deposition that is deposited on dry surfaces during periods of no precipitation as particles or in a gaseous form.
Emissions of sulphur and nitrogen oxides that, in the absence of water in the atmosphere ( i.e., rain), settle to the ground as particulate matter.
The process by which atmospheric gases and particles are transferred to the surface as a result of random turbulent air motions. See also deposition; compare wet deposition.
Deposition onto surfaces by settling out of particles, as opposed to droplets (liquid); also by absorption from the vapor phase.
Atmospheric deposition that occurs when particles settle to a surface, collide with and attach to a surface (adsorption) or are absorbed.
The settling of gases and particles out of the atmosphere. Dry deposition is a component of acid deposition, more commonly referred to as acid rain.
The deposition of pollutants from the atmosphere (such as dust and particulate matter) that occurs during dry weather periods. Dry deposition rates are often drastically different than wet deposition rates.
The transfer of acids and acid-forming substances to the earth's surface by all means that do not involve precipitation. This includes absorption, impaction, sedimentation, and chemical reaction.
The deposit of dry pollutants on a surface; includes particulate pollutants.
delivery of air pollutants in the gaseous or particle phase to surfaces.
