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 Aerosol Mass Spectrometer measurements

This template should be used for both Aerosol Mass spectrometers (AMS) and Aerosol Chemical Mass Spectroemters (ACSM), including instruments such as Q-AMS, C-ToF-AMS, HR-ToF-AMS, Q-ACSM and ToF-ACSM. 

Points to note:

  • To generate Nasa Ames, files it is strongly recommended to use the EBAS Export Tool (an Igor procedure) written by Jay Slowik (Paul Scherrer Institute, Switzerland). The toolkit provides data at Level 0 (measurement time resolution) or Level 2 (re-averaged to hourly data, missing points filled in). The tool requires fully processed ACSM/AMS data.

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: 

acsm.txt

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

Flags commonly used with this format:

Group 9: Missing flags

Flag Validity Description
999 M Missing measurement, unspecified reason


Group 0: Valid data

Flag Validity Description
000 V Valid measurement
