Rebecca,
Sorry for the delay reply.
I checked the uploaded sample file, the problem of this dataset is that the
sigma coordinate is now well defined. Here is the link of the CF sigma
convention:
https://earthdata.nasa.gov/sites/default/files/field/document/cf-conventions_v1.4.pdf
and check the section 4.3 for more detail information.
