missing variables in HRRR data accessing via THREDDS Data Server - thredds

Question

I accessed hrrr data through thredds server as shown here. However, The two needed variables
"Upward long-wave radiation" and "Downward short-wave radiation" are not contained in the accessing dataset. With accessing using AWS, these variables are exist,
