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 heavy metals in precipitation

This format should be used for submitting all relevant heavy metal measured in precipitation, including precipitation amount. 

Points to note

Clicking on a specific line in the example template will provide a detailed explanation and possible options for each of the metadata elements. Please contact ebas@nilu in case of broken links etc.

  • Report precipitation amount from the wet only (or bulk) sampler and the co-located official meteorological rain gauge when available.
  • Include information on both the sampling and analytical instruments.
  • Include information on performance in laboratory inter-comparison in the QA measures.
  • For days without rain, set value to 0.00/flag to 000 for precipitation amount, and value to missing/flag to 890 for the trace elements.
  • EMEP manual: online version

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: 

heavy-metals-in-precipitation.txt

* To validate the file, please use the EBAS Submission Tool

Flags commonly used with this format:

A full list of flags could be found here.

V (valid measurement)I (invalid measurement)M (missing measurement) or H (hidden and invalid measurements).

Group 9: Missing flags

Flag Validity Description
999 M Missing measurement, unspecified reason

Group 8: Flags for undefined data elements

Flag Validity Description
890 M Concentration in precipitation undefined, no precipitation

Group 7: Flags used when the value is unknown

Flag Validity Description
780 V Value below detection or quantification limit, data element contains estimated or measured value. Use of flag 147 is encouraged.
781 V Value below detection limit, data element contains detection limit
782 V Low precipitation, concentration estimated
783 M Low precipitation, concentration unknown

Group 6: Mechanical or instrumental problem

Flag Validity Description
656 V Wet-only collector failure, operated as bulk collector
657 V Precipitation collector overflow. Heavy snowfall/rain shower (squall)

Group 5: Chemical problem

Flag Validity Description
555 V Pollen and/or leaf contamination, but considered valid
556 V Bird droppings, but considered valid
557 V Insect contamination, but considered valid
558 V Dust contamination, but considered valid
559 V Unspecified contamination or local influence, but considered valid
565 I Pollen and/or leaf contamination, considered invalid
566 I Bird droppings, considered invalid
567 I Insect contamination, considered invalid
568 I Dust contamination, considered invalid
591 I Agricultural contamination, considered invalid
599 I Unspecified contamination or local influence

Group 4: Extreme or inconsistent values

Flag Validity Description
440 V Reconstructed or recalculated data
459 I Extreme value, unspecified error
460 I Contamination suspected

Group 1: Exception flags for accepted, irregular data

Flag Validity Description
147 V Below theoretical detection limit or formal Q/A limit, but a value has been measured and reported and is considered valid

Group 0: Valid data

Flag Validity Description
000 V Valid measurement
