I'm guessing this is not possible but I thought I would ask just in case
there is something I missed.
Is it possible to change a dimension from a fixed length dimension to a
record or unlimited dimension in place without having to rewrite the
entire file.
In my case I have a bunch of 2D (lat, lon) or 3D (lon,lat,lev) plus time
netcdf 4 files where time is the last dimension (1 time per file) that I
want to concatenate with the nco utility. The files were created with
time a fixed dimension of length one and are large and nco seems to be
making a copy of the whole file when converting the time to an unlimited
dimension. Looking at the API it doesn't seem it can be done without
making a new file.
