Comment (by jonathan):
As Mark and Jim know, I sent the following reply to Chris by email:
Thanks for your email. I am pretty sure that "measurement" would be a
confusing word to use for model data, because people never describe
simulated values as measurements. That's we chose the more agnostic "data
value". I understand your point but I imagine that many users would not
really understand what was meant by "source estimation field".
In more words, the idea of cell_methods is this: Each cell has a data
value. However, if the quantity itself is continuously varying as a
function of the independent variables, that data value is somehow
representing all the values within the cell. The cell methods says what
statistic of the variation is being used. It could be a point value,
meaning it's a just one value from all those within the cell. It could be
a sum, meaning it's an integral over all the cell (like rainfall
accumulation over time). It could be some other statistic, such as mean or
maximum. Maybe we should just spend more sentences on it, instead of
trying to get away with a single sentence.
