Dear Randy Thanks for your further description. Now I agree with you and John that this is a point feature. I guessed wrongly from your first email that you were describing something like a timeseries. The file records a number of lightning events, each with an energy, area, location, time - have I understood correctly? In that case I suppose the logical structure of the data is
float event_energy(event); event_energy:coordinates="time lat lon"; event_energy:cell_methods="time: sum area: sum"; float event_area(event); event_area:coordinates="time lat lon"; event_area:cell_methods="time: sum area: sum"; float time(event); time:bounds="time_bounds"; float time_bounds(event,two); float lat(event); float lon(event); Is that right? The energy detected applies to a certain region of space-time, so I think "sum" is the appropriate cell_methods, rather than being precisely localised at a particular time and place, in which case "point" would be right. I have put the energy and the area of the event as the data variables, and the time and location as aux coord vars. You might wish to propose new standard names for the data vars.
