Yes, I agree that the usual shared time coordinate variable (supposed to
be monotonic etc) is not quite the right way to do time series of
observations, when there are multiple stations, trajectories, etc.
I have been thinking about how to use netcdf files effectively for
"observation datasets", as opposed to gridded data, and ive written some
ideas here:

Any feedback from this group or beyond would be welcome.
