- Questions regarding "Formatting Meteorological Data for EddyPro" section in guide:
- If the columns mentioned in table 1 Met Tower Variables are not present in the data file, should the write the current processed data to the output path, throw an error message and then exit from the program without further processing?
- EddyPro reads these variables from ghg file, not from the input file from the "formatting met data" section: (1) air temperature from ghg(setup during running eddypro) (2) air pressure from ghg (setup during running eddypro)
- EddyPro input file should contain these variables from met file : (3) relative humidity from met data (RH_Avg) (4) incoming shortwave radiation from met data (SWin) (5) incoming longwave radiation from met data (LWin) and (6) Photosynthetically active radiation (PPFDr) from met data.
- EddyPro additional variables read from met file : (1) air temperature from met data ( RTD_C_Avg, AirTC_Avg)
- Break if dataframe doesnt include 3,4,5,6 and throw a warning for all other variables(1, 2, plus the rest of variables in met data and soil met key) and proceed.
- We choose shf_Avg(1) or shf_Avg(2) based on which variable has min number of NANs. What should we choose if both have equal number of NaNs?
- Air_TC_RTD and Air_TC - match pattern Air_TC* rename to Ta_1_1_1 (first) and Ta_1_1_2 (second). Ta_1_1_1 should always be present
- Soil temp - we currently use TC_10cm_Avg or TC1_10cm_Avg or TC2_10cm_Avg - whichever has min number of NANs. I also see variables named SoilTemp(x)_Avg measurements. Is TC\d*_10cm_Avg the correct variables to be used?
- The variable name Moisture0_Avg (used for EddyPro label SWC) changes with filename / crop type. I think Bethany is working on a table to match these keys. Let me know if I am missing anything here.
- WindSpeed_Avg and WindDir_Avg is not present for 2000 data. What other variable should be used instead? If the timestamp is not 2000, shall we use these variables as such?
- WindSpeed and Wind dir from 2020 onwards will be matched with ghg file - check if column is existing. if not throw a warning and proceed.
- WindSpeed and WindDir for other years are present in met data file
- EddyPro will not use WindSpeed and WinDir from met file. It only uses ghg file values.
- Dynamic naming of met tower variables (SHF_1_1_2) - needs some clarity. I have one note which says these will be fixed by PyFluxPro automatically and another note mentions its manual.
- shf(1)_Avg and shf(2)_Avg will be renamed to SHF_1_1_1 and SHF_1_1_2
- soil moisture measurement (SWC in EddyPro) and soil temp measurements (Ts in EddyPro)
- If the columns mentioned in table 1 Met Tower Variables are not present in the data file, should the write the current processed data to the output path, throw an error message and then exit from the program without further processing?
- In dynamic metadata creation:
- Canopy height data can be taken wither from LAI measurements if completed, or from phenocam images. Phenocam images can be found on the Energy Farm server, directory “Z:\FTP\[Site Name]” As of fall 2018 new phenocams were installed, and images taken using the new cameras are deposited in “Z:\FTP\uief[Site Name]2”
Action items
- Bethany Blakely How do we get the instrument height and instrument separation - create some kind of form to enter the height by technician ?
