Template for Mercury in precipitation (draft)
This format should be used for submitting all relevant persistent organic pollutants (POPs) measured in precipitation
Points to note
Report precipitation amount from the wet only or bulk)sampler and the co-located official meteorological rain gauge when available.
For days without rain, set value to 0.00/flag to 000 for precipitation amount, and value to missing/flag to 890 for the compound.
This template can be used for total deposition measurements also, then use matrix precp+dry_dep. NOTE. If however concentration has been measured, this should be reported together with precipitation
Include information on both the sampling and analytical instruments.
Include information if been part of any relevant laboratory intercomparison in the QA measures.
Please download the .nas file and edit, and remember to keep the .nas file-extension when you
create your datafile:

The three main types of flags in EBAS are:
For data harmonization across the network, the following short list of the flags should be used with this template. It is possible to use several flags at the same time to give detailed information about the data.
|Group 0: Valid data|
|000||V||valid data, no flag|
|Group 1: Exception flags for accepted, irregular data|
|147||V||Below theoretical detection limit or formal Q/A limit, but a value has been measured and reported and is considered valid|
|Group 4: Extreme or inconsistent values|
|Group 5: Chemical problem|
|559||V||Unspecified contamination or local influence, but considered valid|
|599||I||Unspecified contamination or local influence|
|Group 6: Mechanical or instrumental problem|
|656||V||Wet-only collector failure, operated as bulk collector|
|657||V||Precipitation collector overflow. Heavy snowfall/rain shower (squall)|
|Group 7: Flags used when the value is unknown|
|781||V||Value below detection limit, data element contains detection limit|
|782||V||Low precipitation, concentration estimated|
|783||M||Low precipitation, concentration unknown|
|Group 8: Flags for undefined data elements|
|890||M||Concentration in precipitation undefined, no precipitation|
|Group 9: Missing flags|
|999||M||Missing measurement, unspecified reason|
