Dear WRF USERS

I am running WRF-ARW model to make input meteorological data of HYSPLIT Model.
I used GFS 0p25 data which represent whole world.
I made my namelist.wps file like below.
Code:
&share
 wrf_core = 'ARW',
 max_dom = 1,
 start_date = '2016-08-24_03:00:00',
 end_date   = '2016-08-24_12:00:00',
 interval_seconds = 10800
 io_form_geogrid = 2,
/

&geogrid
 parent_id         =   1,   1,
 parent_grid_ratio =   1,   3,
 i_parent_start    =   1,  31,
 j_parent_start    =   1,  17,
 e_we              =  81, 112,
 e_sn              =  135,  97,

 !!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!
 ! The default datasets used to produce the HGT_M, GREENFRAC,
 ! and LU_INDEX/LANDUSEF fields have changed in WPS v3.8. The HGT_M field
 ! is now interpolated from 30-arc-second USGS GMTED2010, the GREENFRAC
 ! field is interpolated from MODIS FPAR, and the LU_INDEX/LANDUSEF fields
 ! are interpolated from 21-class MODIS.
 !
 ! To match the output given by the default namelist.wps in WPS v3.7.1,
 ! the following setting for geog_data_res may be used:
 !
 ! geog_data_res = 'gtopo_10m+usgs_10m+nesdis_greenfrac+10m','gtopo_2m+usgs_2m+nesdis_greenfrac+2m',
 !
 !!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!
 !
 geog_data_res = 'default','default',
 dx = 10000,
 dy = 10000,
 map_proj = 'lambert',
 ref_lat   =  35.88,
 ref_lon   = 127.5,
 truelat1  =  30.0,
 truelat2  =  60.0,
 stand_lon = -98.0,
 geog_data_path = '/media/sol/SAMSUNG/WRF/WPS_GEOG/'
/

&ungrib
 out_format = 'WPS',
 prefix = 'FILE',
/

&metgrid
 fg_name = 'FILE'
 io_form_metgrid = 2,
/

As you can see in namelist.wps, I set smaller domain size than whole world.
Here is the question. If i make meteorological data of HYSPLIT Model using this namelist.wps, the result data,meteorological data, represent only area that i set in namelist.wps?

I should know it to set number of particle options of HYSPLIT.
Please help.
