FillValue issues with kerchunk 1e37=> 9.99999993e+36
See original GitHub issueIn my original NetCDF4 file (HDF5 under the hood) the fill value _FillValue is set to 1.e+37 for 32bit floats, and when loaded into xarray with decode_cf=True, the data values with 1e37 are correctly interpreted as fill values and set to NaN.
In the kerchunk JSON, the _FillValue in the JSON is set to 9.99999993e+36 and when loaded into xarray with decode_cf=True, the data values are not interpreted as fill values, and show up as 9.99999993e+36 (not 1e37 and not NaN).
Pretty confused on what is going on here!
Here is a Reproducible Notebook

OK, so kerchunk is happy to fill in the
_FillValueattribute. I anticipate that in any tool that is not xarray, or with cf decoding off, this will simply be ignored. I’ll make that change, we can rerun the fail case and see if all is good. Next week… 😃
