Variables that do not have a Z dimension should have a levs value of 0.

Variables that do have a Z dimension should have a levs value equal to the znum value specified in the ZDEF statement. The units field is a comma-delimited list of the varying dimensions of the variable. The order of the dimensions listed in the units field is important -- it must describe the shape of the variable as it was written to the SDF data file.

For NetCDf files, this information appears in the output from ncdump next to the variable name. For HDF5 files, this information appears in the output from h5dump as the variable's dataspace. Another option in this example would be to fill the unused Z axis with the histogram intervals:. ZDEF 3 linear 1 In this case, it would appear to GrADS that variable 'hist' varies in Z, but the user would have to remember that the Z levels correspond to histogram intervals and not pressure levels.

The latter technique makes it easier to slice through the data, but is not the most accurate representation. And if you don't have an unsued world-coordinate axis available, then you still have a way to access all the dimensions of your data variable. This entry points to the data file. See the reference page for more details. This entry should have either the 'netcdf' or 'hdfsds' keywords.
