Dear Cathy,

It seems you need two steps:
1. Replace the data values that match the old _FillValue with the new
value, using the cdo command.
2. Replace the attribute _FillValue with the new value, using the ncatted
command.
Having said that, NaN is usually "safer" in that its use causes error,
making your bugs easier to spot.
Hope this helps,
Ryo
