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 Optical Depth Data

Below, you find a file format example that is specific for regular reporting of aerosol optical depth data. 

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 etc.

  • Most of the information entering the header needs to be collected only for the first submission. For the first submission, it is easiest to copy the example, and to adapt it to your station. However, when "recycling" the header for a new submission, please do make sure that the information is current, and update where necessary.

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: 

aerosol_optical_depth.txt

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