Modify WRF input data by the whole nested domain

WRFtailor can modify the WRF input data (grid points) over the whole nested domain. The nested domain is always the smallest one. For example, if there are one parent domain, one subdomain, and one sub-subdomain, the 3rd domain will be selected.

All required settings can be managed by a text file (namelist.wrf).

Example

Modify WRF/Chem emissions data (wrfchemi_d01_2021-01-22_00:00:00, wrfchemi_d02_2021-01-22_00:00:00, and wrfchemi_d03_2021-01-22_00:00:00):

Provide the paths to the files in namelist.tailor:

====================== WRF files and input data =======================

===================================================================

number_of_domains = 3

domain_1 = /home/anikfal/aatrain/wrftailor/wrfchemi_d01_2021-01-22_00:00:00

domain_2 = /home/anikfal/aatrain/wrftailor/wrfchemi_d02_2021-01-22_00:00:00

domain_3 = /home/anikfal/aatrain/wrftailor/wrfchemi_d03_2021-01-22_00:00:00

domain_4 =

domain_5 =

————————————————————————————————-

Set namelist.tailor to modify the values of the desired variables:

=================== Modify by the whole nested domain =================

===================================================================

whole_domain_ON_OFF = 0

target_variable4 = E_CO

target_var_level4 = 1

substitute_variable4 = E_NO * 0

substitute_var_levels4 = 1,

————————————————————————————————-

In the table above, the variable E_CO over the smallest nested domain, will be modified and replaced by E_NO * 0, which turns the values to zero.
