Multidimensional Rasters Missing Attribute Information (ArcGIS)

I downloaded NASA VIIRS/NPP Lunar BRDF-Adjusted Nighttime Lights (VNP46A4) data for use within ArcGIS Pro. I'm trying to input the multidimensional raster into ArcGIS Pro so that I can create a space-time cube, but anytime I try to do analysis with the rasters, it says there's no valid time dimension. There's no attribute data for these layers which is why I'm assuming there's an issue. Does anyone know how to fix this? Is there anywhere I can download these layers that are more optimized for a GIS?

The HDF to GeoTIFF converter only works for QGIS. I need to use ArcGIS Pro. The problem isn't that it's an HDF file; I actually want an HDF file. But I want an HDF file that analysis can be performed on. The files provided by NASA aren't really functional beyond viewing in ArcGIS.

The purpose of the converter tool is to generate files in GeoTiFF format which can be used in ArcGIS. Unfortunately, there is no other option available for this.

Hi there!
Thanks for reaching out. Could you tell me the process you are following and any errors you are receiving? I am running ArcGIS Pro 2.8.0 and I’ve downloaded 4 separate VNP46A4 HDF files to add to a mosaic dataset I created. I had success with appending the data and identifying the time dimension, which covered two separate dates. The process I followed was ‘Create Mosaic Dataset’ then ‘Add Raster to Mosaic Dataset’. For this tool I selected HDF for ‘Raster Type’ and ensured all Variables were added from the file properties. I then selected each file under ‘Input Data’. It executed without error and both the attribute table and the Multidimensional tab have the correct temporal information included. Temporal Profile chart and Sample analysis tool seemed to work correctly.
