Hi
I am wondering whether anybody can help me how I can alter the initial and boundary conditions of temperature.
Thanks,

We provide an utility to change data in netCDF file, including wrfinput and wrfbdy. Please see the code and its usage here:
https://www2.mmm.ucar.edu/wrf/OnLineTutorial/Tools/read_wrf_nc_options.php

Alternatively, you can also use NCK, PYTHON, NCO or any other software package you are familiar to change data in wrfinput/wrfbdy.

Thanks Ming for your suggestion. I will be able to chenge this using NCL. Just wondering whether I need to change in both wrfinput and wrfbdy files. In wrfinput, I can see the variable T and in wrfbdy, I can see some of the T related variables T_BXS, T_BXE, T_BYS, T_BYE, T_BTXS, T_BTXE, T_BTYS, T_BTYE. Do I need to change all of the parameters to change the temperature?

Whether you need to change temperature in the wrfbdy file depends on the sensitivity experiment you will do. In most cases, I believe that both wrfinput and wrfbdy should be changed. Otherwise there will exist inconsistency between the initial data and the boundary forcing.
