Dear Martin Yes, I agree, "interval" is an ambiguous word, unfortunately.

The distinction between those two can already be made like this: - hourly data have coordinates spaced hourly, and cell_methods with "mean" or "point" (depending on wheher they were hourly time-means or instantaneous values at hourly intervals). - daily max of running means have coordinates spaced daily, and cell_methods with "maximum". What we *can't* record in a standardised way is the extra information that the maximum was calculated from running means. We need to do this if there are also daily maxima calculated from other kinds of subdaily data. I apologise if this is frustrating. I am trying only to clarify what is needed in practice!
