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 0)

Points to note:
  • Reference pressure and temperature for flows:
    A level 0 file contains the data as provided directly by the instrument. Since integrating nephelometer setups are designed to alter the aerosol as little as possible, the data are normally referenced to instrument internal temperature and pressure, which are also reported for later conversion to standard conditions of temperature and pressure.
  • Preparation of level 0 nephelometer data:
    The data reported in a nephelometer level 0 file are calibrated to particle free air and a span gas of known scattering coefficient, and the calibration is confirmed by regular tests typically once per month or more often. Otherwise, the data are uncorrected, e.g. not corrected for angular truncation.

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_lev0.txt

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