Submit DataData ReportingTemplatesCategoryHeavy MetalsHeavy metals in aerosol particle-phase    July 16, 2020

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 aerosol particle-phase

This format should be used for submitting all relevant heavy metal measured in aerosols

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.

  • Include information on both the sampling and analytical instruments.
  • Include information on performance in laboratory intercomparion in the QA measures.
  • Include filter type and sample preparatidon
  • 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:
