I think you need a definition of the cell boundaries also: http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/cf-conventions.html#cell-boundaries >> float t_an(time, depth, lat, lon) ; >> t_an:standard_name = "sea_water_temperature" ; >> t_an:long_name = "Objectively Analyzed Mean" ; >> t_an:comment = "Objectively analyzed climatologies are the >> objectively interpolated mean fields for an oceanographic variable at >> standard depth levels for the World Ocean." ; >> t_an:cell_methods = "area:mean depth:mean time:mean" ; >> t_an:grid_mapping = "crs" ; >> t_an:units = "degrees_celsius" ; >> t_an:FillValue = 9.96921e+36f ; from this, I can tell that the value is a mean over area, depth and time -- but what area? what depths? what time? I'd probably assume the area of a single grid box (though that's not totaly defined here, and probaly the full water depth, but I'm not at all sure about time: mean over one time step?> monthly mean? yearly? this brings u sa question for me: how would one define a cell bounds that was "the full water depth". -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov _______________________________________________ CF-metadata mailing list CF-metadata@cgd.ucar.edu http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
