Hello; I had a number of questions regarding interpretation of time and vertical axis in a given NetCDF file (vertical especially for ocean current data)
1) What should be the default interpretation of the timestamps on a given time axis when there is no explicit CF convention based information in a given file (in COARDS format we can say) Should they be taken the centers of time intervals, or the starting point of the intervals ? 2) Should the corresponding values be assumed to be the average of values on that interval or measurements at that specific timestamp? 3) For vertical layer if I have the following depths: [0.0, 10.0, 50.0], should this be interpreted as three layers with boundaries [0.0, 10.0] [10.0, 50.0] [50.0, +inf] ? 4) And finally, is it usual to apply interpolation in these axes (time, vertical) or just locating the closest time record and vertical layer is the general approach since they are in general the averaged values on that time interval or on that vertical layer? Thanks in advance, Yilmaz _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
