But that's what you want to do.įerret uses the CF conventions for netCDF files, and there's much In the warning message, Ferret is telling you you're making a change For example, if one of my masks was 9 voxels large and the other one was 15 voxels, with a 2x2x2mm resolution (or 8 cubic millimeters per voxel), the output would look like this: 9 72.000000 15 120. *** NOTE: Redefinition may alter apparent The first number is the number of voxels, and the second number is the volume, in cubic millimeters. *** NOTE: grid GHU1 used by data set my_data UNITS=days/T0=, and even change the values of the The next dedup job will check the integrity of the remaining chunks: start-dedupjob -Volume C: -Type DataScrubbing. The most simple case just nails down theĭefinition as a T axis. You can change the definition of the coordinate axes of a grid in What dim1 and dim2 represent thus depends on your data. But as you found, when the data is written out it is Use the data in your Ferret session, and it would behave as you

For thisįile you are correct to try USE/ORDER=xyt which tells Ferret toĭefine the grid for the variables with directions x,y,t. In the example above, if dim1,ĭim2, dim3 would not be listed under the variables section. Some files have dimensions, but no coordinate variables.

The dimensions are listed, then the third dimension needs anĪttribute that Ferret and other software would use to determine that The downside is that we must calculate the indexes in the output array. This allows us to iterate multi dimensional arrays as if they were flat. Attributes 'standard_name', 'long_name', or 'axis' wouldĪlso tell it the correct direction. 2 Answers Sorted by: 4 I want to present an alternative solution. Would be enough to tell Ferret that these are X, Y, and Tĭimensions. Assuming your cube has 4 dims dim1, dim2, dim3, dim4 and the measures dim has elements: Kgs, metres, GroupAverage And assuming you want to average on a consolidated element 'Total of dim3' on dim3, your rule would look like this. In addition to being dimensions of the grids of the data, they areĪlso defined as variables with attributes. That will list the netcdf header for the file. If you execute the unix command, > ncdump -h myfile.nc
