Terrestrial and aquatic ecosystems receive Nr inputs from the atmosphere through wet and dry deposition.

About half Britain's sulphur rains down as wet deposition and half is dry fallout.

The resulting sulfuric and nitric acids can fall as wet or dry depositions.

Deposition of the pollution plume components to the underlying surface can be defined as either dry or wet deposition:

Wet removal of both gases and aerosols are both of importance for wet deposition.

It can be divided into two sub-processes: dry and wet deposition.

In wet deposition, atmospheric hydrometeors (rain drops, snow etc) scavenge aerosol particles.

This means that wet deposition is gravitational, Brownian and/or turbulent coagulation with water droplets.

Different types of wet deposition include:

Nowadays, mirrors are often produced by the wet deposition of silver (or sometimes aluminum via vacuum deposition) directly onto the glass substrate.
