Topic: Regridding + Fill Values

Hi All,
I am working with a dataset that includes non-conventional fill values (65534 and 65535). When regridding, these fill values get merged into the regridded dataset. Is there any way to identify non-standard fill values in the xESMF regridder to avoid this problem? Thanks in advance!

Could ask on github: https://github.com/pangeo-data/xESMF/issues

Why not simply replace the fill values with NaN's prior to regridding?

@Matt Long I can do that! I was curious whether an option to specify the fill value was available in the regridder function. Sounds like there is not.
