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 Integrating Nephelometer Data (level 2)

Below, you find an example of a data file reporting measurements of the aerosol scattering coefficient measured by an integrating nephelometer. The parameters to be included in a regular data submission have been determined by an instrument specific GAW expert group.

Points to note:

  • Sample relative humidity:
    The GAW aerosol Scientific Advisory Group strongly recommends to take measures ensuring a sample relative humidity (RH) of less than 40%. This recommendation intends to make the data comparable across the network, which otherwise would be a strong function of the highly variable sample RH. However, you may still report data as valid where this recommendation isn't met. In this case, please flag the concerned data points with the 640 flag ("Instrument internal relative humidity above 40%").
  • When calculating average values, e.g. hourly, from measurements with higher time resolution, please disregard any invalid measurements. Any informative flags, e.g. local contamination, occuring at any time during the average period need to be copied to the average value.

  • Submitted data will be checked for boundaries, the current specification for boundary checks can be found here





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: 

integrating-nephelometer.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.
