information on creating a dynamic metadata file. But one thing concerning the matching of timestamps remains unclear. Maybe because English is not my native language, I don’t know.
My setup is as follows: The input files (raw data) span 30min each and the name of each file contains the END OF INTERVAL which it covers. I need to vary displacement height and roughness length depending on the wind direction for each 30min averaging interval. Therefore it may change quite often.
Example with 3 files (yyyymmddHHMM.csv)
If the change in the metadata occurs between file 2 and 3, do I need to write
a) 201704181030 (end of file 2)
b) 201704181100 (end of file 3)
in the dynamic metafile, so that EddyPro uses old values for the second and new values for analyzing the third file?
sorry for the late reply.
EddyPro looks for the closest timestamp in the dynamic metadata file that is *strictly earlier* than the END of the current averaging interval (which in your case coincides with the timestamp in the raw file names).
Thus, using the timestamp (b) will instruct EddyPro to use the old value for files 1 and 2, and the new value for file 3.
In the dynamic metadata file, make sure you write the timestamp in the correct format, as per the documentation.
Hope this helps.
