Template for inorganic air/aerosol chemistry (filter-based)


This format should be used for submitting all relevant inorganic components (sulphur, nitrogen, base cations and sea salt ions)
measured in air and aerosols with a filter-based system. Typically a three stage filterpack sampler (the EMEP reference method)
or a denuder system, but also chemical speciation of one filter systems like PM10 and PM2.5.


Points to note:

  • Report sum of nitrogen compounds, i.e. HNO3+NO3 and NH3+NH4 in addition to the concentration of the individual components
  • Include information on filter type(s) and coating solution(s).
  • Include information on both the sampling and analytical instruments
  • Include information on performance in laboratory intercomparison, i.e in EMEP and WMO/GAW for the respective year

    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:
