Error while running WPS with HRRR data

Postby VRavi » Fri May 19, 2017 2:32 pm

Hi,

I'm trying to run WRF with High Resolution Rapid Refresh (HRRR) data. HRRR forecast is available every hour for next 18 hours.
When I run WPS with 00Z forecast, I'm able to run WPS and WRF successfully. However, if I do the same with, say, 12Z forecast, wps fails. In particular, while ungrib.exe reads in all GRIBFILE.xxx files, it creates intermediate files for hours only on the start_date. Thus, say, for HRRR input of 2017/05/17 at 12z, I only get intermediate files till 23z of 2017/05/17, even though namelist.wps specifies correct start and end date. The namelist.wps file is pasted below:

Code: Select all
&share
 wrf_core = 'ARW',
 max_dom = 1,
 start_date = '2017-05-16-12:00:00','2006-08-16_12:00:00',
 end_date   = '2017-05-17-06:00:00','2006-08-16_12:00:00',
 interval_seconds = 3600
 io_form_geogrid = 2,
 debug_level = 1500
/

&geogrid
 parent_id         =   1,   1,
 parent_grid_ratio =   1,   3,
 i_parent_start    =   1,  31,
 j_parent_start    =   1,  17,
 e_we              =  285, 380,
 e_sn              =  258, 344,
 geog_data_res = 'default','default',
 dx = 4000,
 dy = 4000,
 map_proj = 'lambert',
 ref_lat   =  44.98,
 ref_lon   = -118.00,
 truelat1  =  30.0,
 truelat2  =  60.0,
 stand_lon = -121.0,

 geog_data_path = '/home/user_name/models/WRF3.8.1/BUILD/GEOG/'
/
&ungrib
 out_format = 'WPS',
 prefix = 'HRRR2WRF',
/

&metgrid
 fg_name = 'HRRR2WRF'
 io_form_metgrid = 2,
/


Any thoughts why I can't get WPS to process all 18 hours? I greatly appreciate any help on this.

Thanks,
Vikram

Hi

I am also facing the issue in running WRF/WPS with HRRR data. I can run ungrib and metgrid, but the NUM_METGRID_SOIL_LEVELS in my metgrid output files (met_em.d01.*) are zero (NUM_METGRID_SOIL_LEVELS = 0). So I am facing issue in running real.exe.

Please tell me the value of NUM_METGRID_SOIL_LEVELS in your met_em.d01.* files. Also please tell me where I can find right vtable, possible please send you vtable to chanspace2020@gmail.com.

Thanks
