Hi all, I had sent this previously, but I was not registered to the mailing list at the time and I fear it may still be awaiting moderator approval.
Apologies if this was in fact answered! Thanks, Daley From: Calvert, Daley Sent: 31 March 2015 16:27 To: '[email protected]' Subject: Use of "interval" in cell_methods to imply bounds of prior operations Hi all, I am attempting to improve the compliance of output from an ocean model I/O server with the CF standard. In particular I am looking to improve the representation of time operations performed by the server, which can be applied up to two consecutive times for statistics such as "5-day mean daily maximum" and such forth. I would like to represent the cell_methods as generically as possible, listing the consecutive time operations and the frequency relating to the first time operation. For example, a 10-day mean of 2-day maxima might be written as: cell_methods = "time: maximum over days (interval: <timestep size>) time: mean over days (interval: 2 days) However I can't tell whether it is correct to use the interval comment to imply that the maximum has been calculated every two days prior to the 10 day mean. Any advice on this would be very welcome!
