Hi.

I have a situation where there are multiple measurements within a 4D lon/lat/z/t volume, for which a single value is produced by calculating the weighted mean of all the measurements. This mean is of the form

(sum over i of wi * vi) / (sum over i of wi)

where wi is the inverse of the uncertainty in the measurement vi.

So how do I represent that within cell_methods? Would it be

lon lat z t: mean (uncertainty weighted)

or something else?

Grace and peace,

Jim
