Reproduced also in my environment.

Selected repr of your dataset is python <xarray.Dataset> Dimensions: (N_CALIB: 1, N_HISTORY: 0, N_LEVELS: 1007, N_PARAM: 3, N_PROF: 33) Dimensions without coordinates: N_CALIB, N_HISTORY, N_LEVELS, N_PARAM, N_PROF Data variables: ... SCIENTIFIC_CALIB_DATE (N_PROF, N_CALIB, N_PARAM) object b'20150514141619' ... HISTORY_INSTITUTION (N_HISTORY, N_PROF) object ... It seems the data variable in concern, such as ds['HISTORY_STEP'], is 2-dimensional but one of the dimensions N_HISTORY is size 0.

~~Currently, xarray does not handle such zero-length n-dimensional arrays. Maybe we need to drop such variables when reading?~~

EDIT: This was wrong. xarray should handle 0-size nd-array.

@shoyer, @fmaussion, any idea?
