Treatment of missing values in emission data

[xli585]

I modified the emission data for OC, SO2 , and BC in the atm component of CESM2.1.4 F2000climo_f09_f09; however, I noticed that the official emission data used by CESM contains no missing values or associated dimensions, for example:


But the data I obtained from the CEDS website has missing values:


I would like to ask how these missing values should be handled?


Currently, I have set all missing values to 0 and manually removed the missing value dimensions of the variables by:

delete(num_ene_ind_so4_vert@_FillValue)


The model can run successfully, but I am unsure whether this will affect the results.

Hi There!
Setting missing values to zero and removing the missing value from variable metadata is correct for CESM input. We reprocess all emissions for CESM use (like CEDM, QFED etc). Note, the model throws errors or fails to run if using NaN in emission files.
