Hi,
I am trying to run the SOCA observer offline.
I am currently using the model history file as the input model file instead of the restart file from GEFSv13. Is there anything I should be aware of when using the history file?
One issue I noticed is that the _FillValue in the restart file (0 for Temp) and the history file (-1e+34 for temp) are different. I tried changing the Fill Value in fields_metadata.yaml to match the _FillValue in the history file, but it still does not work. Some HofX have values of -1e+34 or something like -0.6e+34.
Does anyone know how to configure SOCA/HofX to recognize the _FillValue of the model input file and exclude those values (e.g., -1e+34) so that they are not treated as valid values of the variable?
I am suspecting that the FillValue is used where the land mask is but the FillValue may not be considered as missing value inside GeoVaLs/HofX. I can see the Min value of the HofX is now -1e-34 in the log file. Any suggestions or guidance would be greatly appreciated. Thank you so much!
This is what inside the log file:

H(x): WOD_T:waterTemperature : Nobs= 122285, Min=-1.000000e+34, Max= 3.001321e+01, RMS= 9.291055e+32
