Atmospheric Deposition Gauges

Atmospheric Deposition Gauges, Particulate Fallout, and Precipitation Collector have been developed to collect representative samples of dry and wet atmospheric particulate fallout for subsequent analysis.

Deposit Dust Gauge or Particulate Precipitation Collector

The design and development of the collectors are based on an evaluation of similar equipment in use in various countries, including available wet precipitation collectors for meteorological purposes. In addition to the given performance criteria, factors such as construction materials, ease of handling and transportability determined the shape and dimensions of the collectors. The Fallout Collector has been considered by ISO (International Standardization Organisation) for adoption as an international reference collector for particulate fallout. Its design is according to the recommendations of ISO as the present use of materials and procedures permit. (ISO/DIS 4222.2).

The mounting stand can be used for both collector types. Its design allows both collectors to have the same position relative to the bird ring. The stand is adjustable in height so that the collectors can always be adjusted to the prescribed height above ground (for instance when the snow depth varies), and to facilitate the changing of collectors.

The Precipitation Collector is not designed to be used in freezing conditions. During freezing conditions, when the evaporation losses are low, the Fallout Collector can be used as precipitation collector as well.
