Hello Cristophe,

To be absolutely clear, I'm saying the data should be stored in the NetCDF in 
Dobson Units, that the units parameter attribute in the NetCDF file should be 
Dobson Units, but that the canonical unit in the Standard Names List and 
therefore the units mapped in our server should be moles per square metre.

Cheers, Roy.

Dear Roy,

Do you mean that the total ozone values should be given in moles per
square metre in the NetCDF files themselves? Or do you mean that I
should simply add a specific comment in the unit parameter attribute to
make clear that the values are provided in Dobson Unit?
The Dobson Unit is quite common for total ozone users and I'd prefer to
stay with this unit if possible.

Cheers,
Christophe
