Three ways to prepare your data for Voxel Layer (esri.com)
The NetCDF format offers a lot of flexibility in terms of data storage. However, this flexibility also makes it the proverbial ‘wild wild west’ of data formats. The data needs to be compliant to the Voxel Layer data requirements to visualize it correctly as a voxel volume.
Supported voxel formats - ArcGIS Pro | Documentation
NetCDF data must follow the Climate and Forecast (CF) convention.
Currently, only CF-compliant netCDF data with no auxiliary variables as a data source is accepted as a source for a voxel layer.
