Request for guidance on extracting temperature, humidity, wind speed at specific heights in WRF Model

[Minkyu Lee]

I am currently working with the WRF model and would like to modify a module to directly extract temperature, humidity, and other variables at specific altitudes (e.g., 80m, 100m, 120m).

Could you please advise on which module I should modify and how to modify it in order to retrieve these variables at the specified heights?

Any guidance or pointers to relevant documentation would be greatly appreciated.

Thank you in advance for your help!

if you know python i would recommend that tool

You need to do vertical interpolation, that is, interpolate WRF model level data to specified height levels.

UPP is the most convenient package to use. Please take a look at the the website below, where you can download this package and get support from NOAA.

Some other options include NCL and Python, both of which can also conduct vertical interpolation.

There is a third option. You can use &diags section of the namelist.input to specify the AGL heights that the model itself will write directly into output stream. Check:

@ meteoadriatic

Great Suggestions, ---- this is the convenient way to get data in height levels !
