    1111 ||   parent_id=1,1
    1212* parent_grid_ratio  --> It is a list of integers specifying for each domain the nesting ratio relative to the domain's parent.   
     13
    1314 ||   parent_grid_ratio=1,3
    1415* i_parent_start, j_parent_start --> Coordinates of the lower left corner of the nest in the domain's parent.   
     16
    1517 ||   i_parent_start=1,16, j_parent_start=1,34
    1618* e_we -->  It represents the nest’s full west-east dimension. For nested domains, e_we must be one greater than an integer multiple of the nest's parent_grid_ratio   
     19
    1720 ||   e_we=60,82
    1821* e_sn --> It represents the nest’s full south-north dimension. For nested domains, e_sn must be one greater than an integer multiple of the nest's parent_grid_ratio. 
     22
    1923 ||   e_sn=81,112
    2024* dx --> Number specifying the grid distance in the x-direction where the map scale factor is 1. It should be in meters for the 'polar', 'lambert', and 'mercator' projection, and in degrees longitude for the 'lat-lon' projection. 
     25
    2126 ||   dx=0.15
    2227* dy --> Number specifying the grid distance in the y-direction where the map scale factor is 1. As stated for dx, this value should be in meters for the 'polar', 'lambert', and 'mercator' projection, but for the 'lat-lon' projection, it should be in degrees latitude.   
     28
    2329 ||   dy=0.15
    2430* map_proj --> Name of the projections available 'lambert', 'polar', 'mercator', and 'lat-lon'   
     31
    2532 ||   map_proj='lat-lon'
    2633* ref_x, ref_y --> Location of the latitude and longitude of reference for the domain   
     34
    2735 ||   ref_x=1, ref_y=1
    2836* ref_lat, ref_lon --> Reference coordinates of the domain.   
     37
    2938 ||   ref_lat=-8.85, ref_lon=24.1
    3039* pole_lat -->  For the latitude-longitude projection, it represents the latitude of the North Pole with respect to the computational latitude-longitude grid in which -90.0° latitude is at the bottom of a global domain and 90.0° latitude is at the top.
     
    3241* stand_lon --> A real value specifying the longitude that is parallel with the y-axis in the Lambert conformal and polar stereographic projections. For the regular latitude-longitude projection, this value gives the rotation about the earth's geographic poles.
    3342* geog_data_path --> Path to the directory where the geographical data directories may be found.   
     43
    3444 ||   geog_data_path='$HOME/WRF/wps_topo/geog'
    35

    3746Also, the GEOGRID.TBL file is needed to be present into a folder called geogrid, in the same place where geogrid is going to be executed. The final structure is the following:
