Hi Jim,

I considered that, but doesn't that indicate to someone who isn't already aware of the actual time-period covered that data was used starting 2000-12-01 and ending in 2010-03-01, even though data from the months 2000-01 and 2000-02 and 2010-12 also were included in computing the climatologies?

best regards,
Karl

Karl,

I think you should be able to handle this in the bounds variable. If you write the first entry as "2000-12-1", "2010-03-01", doesn't that describe things correctly?

Grace and peace,

Jim

Dear CF community,

In representing the seasonal climatology based on data available for the period January 1, 2000 through December 31 2010, what would be the correct climatology_bounds?

climatology_bounds = "1999-12-1", "2011-3-1",
                                    "2000-3-1", "2010-6-1",
                                    "2000-6-1", "2010-9-1",
                                    "2000-9-1", "2010-12-1" ????

I would note that this seems to capture the idea that we are reporting seasonal means, but it also seems to indicate that this is based in part on data from Dec. 1999 and Jan.-Feb. 2011, when it isn't. Is this the best I can do? [Of course the convention can never tell us if data are complete in forming a climatology. If 1 year were missing, this would not affect the attributes.]

I suppose the in the cell_methods attribute ("time: mean over days time: mean over years" I could add non-standardized information (as permitted by CF), for example: "time: mean over days time: mean over years (with data from the period 2000-1-1 to 2011-1-1)"

thanks for any suggestions,
Karl
