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

For example, dry deposition is the dominant atmospheric input of sulphur to England except in high-rainfall areas.

A year later, the researchers simplified the technique and started using dry deposition, avoiding the stage when graphene floated in a liquid.

The latter name appeared because the dry deposition resembles drawing with a piece of graphite.

Wet and dry deposition is also calculated as a function of local rain intensity and turbulence levels.

Plant shoots form a sink for atmospheric sulfur gases, which can directly be taken up by the foliage (dry deposition).

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

Acid deposition also occurs via dry deposition in the absence of precipitation.

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