I wondered about doing that too. I didn't do it because it seemed to me that the area of the event was really a measured quantity i.e. a data variable, rather than being a property of the space of measurement. But it could be done as you describe. Would you describe the lightning area as a "cell_area"? If not, I think it is probably not a cell_measure. > (2) > Should the CF convention standard be updated to state that a featureType of > "point" can make use of cell constructs ? Currently chapter 7 starts "When > gridded data does not represent ?..". Perhaps we should drop the word "gridded"! It is not really clear what it means, I would say. You describe your dataset as not gridded, because it is not a structured grid, but it's still got cells, so cell_methods could apply. cell_measures could definitely apply too, even if the cells are not in a structured grid. They may still need to be averaged, integrated, etc., for which the metrics are useful.
