9.9692099683868690e+36f is the fill-value (attribute "_FillValue") for 
netCDF variables of type NC_FLOAT.  Values that you do not explicity set
will have this value.

What is the size of the resulting netCDF file?  If it is 5000 bytes or
less, then would you please send me an ncdump(1) of the file.  If it is
larger than that, then please modify your program so that the resulting
netCDF file still has the problem and then send me an ncdump(1) of the
resulting netCDF file
