I have a user unable to use a netcdf file with our code.

It turns out that the file works just fine when read, but if you try to
open it for writing, it chokes:

(this is the netCDF4 Python lib, version 1.6.5, which seems to be the
latest release)

I get:
In [3]: netCDF4.Dataset('
cmems_mod_nws_phy_anfc_0.027deg-3D_P1D-m_1727700325546.nc', 'r+')
---------------------------------------------------------------------------
OSError                                   Traceback (most recent call last)
Cell In[3], line 1
----> 1 netCDF4.Dataset('
cmems_mod_nws_phy_anfc_0.027deg-3D_P1D-m_1727700325546.nc', 'r+')

File src/netCDF4/_netCDF4.pyx:2469, in netCDF4._netCDF4.Dataset.__init__()

File src/netCDF4/_netCDF4.pyx:2028, in netCDF4._netCDF4._ensure_nc_success()

OSError: [Errno -103] NetCDF: Can't write file: '
cmems_mod_nws_phy_anfc_0.027deg-3D_P1D-m_1727700325546.nc'

Any idea how I can get more info as to what's wrong with it?

Again, we have had no problems reading the file.

Thanks,
- CHB

File is 1.2MB, (not huge by today's standards?) so I've attached it here if
anyone wants to take a look.
