[CF-metadata] Recording "day of year on which something happens"

Dear Jonathan, David, Jon,

I would be in favour to changing the  sum cell method to something else, as it took me a while to grasp that "sum" is the opposite of "point". But having a cell_method specifying "cell" as the method could very well be as confusing. But how about "cell_total" (to close to "accumulation"?), "cell_extent", "all_cell", "areal_extent" or similar, possibly without underscore?

Perhaps it would be better to continue this conversation in a new thread, under a better topic header?


Kind regards,
Lars

Dear David and Jon

"accumulation" is certainly extensive, but I think it is rather specific - this method might not be an accumulation, which is a sort of integral. But I agree that it should be a noun. It's being opposed to the "point" method. What about "cell" or "extent"?

Best wishes

Jonathan
