I think I haven't understood what this name really means, sorry to say. I
was guessing it meant the water present in ambient aerosol. But perhaps
that is wrong?

I agree with you about "emission".

Could you modify the netCDF files afterwards using ncatted for instance?

That's very good news - thanks to your effort in large measure, I expect.
