The example template given below contains the metadata fields that are commonly included when reporting data related to this specific template. Some of these metadata elements may not be relevant for your data reporting, like AIRS station ID for stations outside North America or the various QA measure data when there is no QA measure for the data. Such metadata elements could be let out. If you want to include additional metadata elements that are not given in the example template, there is a complete list here.  In case of any doubt about such additional metadata, please consult the EBAS team!

Template for submission of inorganic precipitation chemistry measurements

This format should be used for submitting all relevant inorganic components (sulphur, nitrogen, base cations and sea salt ions)
measured in precipitation, including pH, conductivity and precipitation amount. Typically a wet only sampler is used, which is the
EMEP reference method, but also bulk sampler is commonly used. It is important to measure and report all major ions and pH
to be able to calculate the ion balance for quality assurance purposes.


Points to note:
  • Report precipitation amount from the wet only (or bulk) sampler AND the co-locoated official meteorological rain gauge
    when availible.
  • Include information on both the sampling and analytical instruments.
  • Include information on performance in laboratory intercomparion, i.e in EMEP and WMO/GAW in the respective year. This should be documented in the QA metadata elements.
  • For days without rain, set value to 0.00/flag to 000 for precipitation amount, and value to missing/flag to 890 for
    the chemical species.

Downloading template as text file

You could download the template and start to modify the text with your own metadata. Due to limitations of the online portal we could not provide files with the .nas file extension. So please download the text file and edit, and remember to use the .nas file-extension when you create your datafile: 

inorganic-precipitation-chemistry.txt
