Submit DataData ReportingTemplatesCategoryMeteorologylevel2    October 1, 2020

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 meteorological parameters

This format should be used for submitting data for various meteorological parameters, like atmospheric pressure,
temperature, wind (speed and direction), relative humidity and radiation.

Typically the meteorological monitoring are done by an automatic weather station (AWS) delivering hourly
 average values of the meteorological parameters.

Points to note:
  • Temperature should be reported in K, pressure in hPa, wind speed in m/s, wind direction in
    degrees and relative humidity in per cent (%).
  • Note that the calculation of wind gust could vary between instruments/stations. Thus, it is recommended
    to add a short text about the definition of reported wind gust.
  • "precipitation amount" refers to the accumulated precipitation amount in the period between
    the start time and end time (e.g. daily precipitation amount for daily samples).
  • Use one of the instrument types listed here, where aws stands for automatic weather station
  • Use metadata element "Gust definition" to describe the mathematical algorithm defining the wind gust. More information could be found here.
  • 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: 


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


Flags commonly used with this format:

Most of the flags in EBAS are designed for measurements of chemical species and are not relevant for meteorological
data. Typically, the meteorological data are given with flag 000 for valid data and flag 999 for missing observations.
Technically, one could however use certain flags that may be relevant as specified in the list of predefined flag values.

Group 0: Valid data

Flag Validity Description
000 V Valid measurement

Group 9: Missing flags

Flag Validity Description
999 M Missing measurement, unspecified reason
