Dear Martin The case of anomaly is a good use case. It could be indicated by a standard name modifier, as you say, but I agree with Nan that it should be a specific one i.e. "anomaly" rather than generic. However in that case we have so far been adding new standard_names instead of using a modifier, viz
air_pressure_anomaly air_temperature_anomaly geopotential_height_anomaly surface_temperature_anomaly As you see, we have not so far been flooded with requests for these, even though in principle it could be relevant for any quantity. Following the usual pragmatic approach, I would argue that we don't yet need a general solution for this particular case; we can just add more standard names if you need some.
