Question about MPAS-JEDI (IODA) data structure

[ep-98d]

I would like to use mesonet data for data assimilation, and I have a question regarding the HDF5 data format that IODA would understand. According to the documentation and examples, airTemperature and soilTemperature are shown as scalar value. Could these be a vector? The mesonet data contains the following data

air temperatures at 0.5m, 2m, 10m (above ground)
soil temperatures at 0.05m, 0.1m, 0.2m, 0.3m, 0.4m, 0.5m, 0.6m, 0.75m, 1m (depths).

Where can I find some examples that would accommodate this

Here is the HDF5 I made for reference. The file only contains surface and above ground properties.
