Modify WRF input data over a list of points

WRFtailor can modify the WRF input data (grid points) over a list of points specified by pairs of latitudes and longitudes, by providing the exact new values for each point to replace the default value.

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 list of points ======================

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

points_list_ON_OFF = 1

target_variable3 = E_NO

target_var_level3 = 1

latitudes_list = 33.6, 37.5, 36.94, 37.2, 32.8, 34.2

longitudes_list = 49.55, 50.11, 53.22, 54.33, 54.8, 50.9

point_values = 2000, 2000, 2000, 2000, 2000, 2000

————————————————————————————————-

In the table above, the variable E_NO over a list of points specified by pairs of latitudes and longitudes, will be modified and replaced by point_values.
