Quality flags are attached to variables using the ancillary_variables att of the data variable. If several data variables had the same quality flags and dimensions, they could all point to the same quality variable. Perhaps the problem is that the different variables have different standard names, and this means the quality variables would also have different standard names (and therefore could not be the same variable)? If that is the problem, perhaps we could find a way round it. Or have I missed the point? Best wishes Jonathan
