How to output surface temperature using ncdump in WRF 4.3.3?

[Daito]

Hello,
I am trying to check the surface temperature from a WRF output file using ncdump, but I’m not sure which variable corresponds to surface temperature and how to properly extract it.
I am using WRF v4.3.3 with the urban canopy model enabled (sf_urban_physics = 1).
I would like to:

• Know the correct variable name that represents surface temperature.
• Understand how to extract it using ncdump (e.g., ncdump -v VARIABLE_NAME wrfout_d01_...).

Also, is it possible to get urban surface temperature directly if UCM is used?
Any guidance would be appreciated.
Thank you!

Hi,
First I'd like to apologize for the long delay in response, and thank you for your patience.

The surface temperature should be represented by the T2 values, which is temperature at 2 meters - essentially the surface. This should be the same for urban areas, as well. The 'ncdump' command you mention above should be sufficient to get the output for this (i.e., ncdump -v T2 wrfout*). To quickly visualize it, you can use ncview (ncview wrfout*).
