Modify the area inside a bounding box

WRFtailor can modify the WRF input data (grid points) inside a bounding box specified by latitudes and longitudes. by providing the desired variable to be modified and a polynomial to replace the values of the desired variable.

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

Example

Modify WPS geographical data (geo_em.d01.nc and geo_em.d02.nc):

Provide the paths to the files in namelist.tailor:

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

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

number_of_domains = 2

domain_1 = /home/anikfal/extra_codes/SR/emissions/wrfchemi/geo_em.d01.nc

domain_2 = /home/anikfal/extra_codes/SR/emissions/wrfchemi/geo_em.d02.nc

domain_3 =

domain_4 =

domain_5 =

————————————————————————————————-

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

====================== Modify by bounding box =========================

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

bounding_box_ON_OFF = 1

target_variable2 = ALBEDO12M

target_var_level2 = 1

substitute_variable2 = ALBEDO12M * 3

substitute_var_levels2 = 1,

north_lat = 35

south_lat = 34

west_long = 48

east_long = 51.5

————————————————————————————————-

In the table above, the variable ALBEDO12M in the area inside a bounding box specified by north_lat, south_lat, west_long, and east_long, will be modified and replaced by ALBEDO12M * 3. substitute_var_levels2 specifies the levels for ALBEDO12M, which is the month of the year.

Parent domain and nested domains for the WRF input data (geo_em):

Nested domain will be tailored as shown below:
