When I set namelist.input
num_metgrid_levels = 32,
It pops up an error like this.

Note that the vertical level must be the same for all the met_em files. in yoir case, apparently that some data have 32 levels while other data have 27 levels. Please double check your data and make sure they all have the same number of vertical levels.

Just in case you don't know, WPS provides the utility mod_levs.exe to process data with different vertical levels. please take a look at Chapter 3: WRF Standard Initialization

Please follow the instruction to process your data and pot them on the same vertical levels. Let me know if you still have troubles regarding this issue.
 
I still don't really understand how mod_levs.exe works.
What I understand is
1) Let me define namelist.wps
&share
wrf_core = 'ARW',
max_dom = 2,
start_date = '2019-05-01_00:00:00','2019-05-01_00:00:00'
end_date = '2019-09-01_00:00:00','2019-09-01_00:00:00'
interval_seconds = 21600,
debug_level = 0,
io_form_geogrid = 2,
/

&geogrid
parent_id = 1, 1,
parent_grid_ratio = 1, 3,
i_parent_start = 1, 17,
j_parent_start = 1, 48,
e_we = 68, 73,
e_sn = 78, 67,
geog_data_res = 'default','default',
dx = 27000,
dy = 27000,
map_proj = 'mercator',
ref_lat = 13.692,
ref_lon = 100.750,
truelat1 = 16.729,
truelat2 = 16.729,
stand_lon = 101.886,
geog_data_path = '/project/common/WPS_Static/geog'
/

&ungrib
out_format = 'WPS',
prefix = 'FILE',
pmin = 5000,
/

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

&mod_levs
press_pa = 201300 , 200100 , 100000 ,
95000 , 90000 ,
85000 , 80000 ,
75000 , 70000 ,
65000 , 60000 ,
55000 , 50000 ,
45000 , 40000 ,
35000 , 30000 ,
25000 , 20000 ,
15000 , 10000 ,
5000 , 1000
/


2) Run geogrie -> ungrid -> metgrid
3) define namelist.input
&domains
num_metgrid_levels = 24,
4) Run real.exe -> wrf.exe
Did I understand correctly?

This utility should be employed to process intermediate files (output files of ungrib.exe).

"press_pa" is used to specify a list of levels you want to keep

You can run this program by ./mod_levs.exe old-intermediate file new-intermediate file

After running this program, your intermediate files should have the same vertical levels (specified by press_pa)

Then you can move on to run metgrid.exe, real.exe and wrf.exe.
 
Hi I am trying to run the mod_levs.exe
So I gave the command
./mod_levs.exe GRIB.AAA GRIB.AAA and I have the namelist.wps in the same directory
But it is showing me an error : Didnt recognize format version of data in /home/../WPS/GRIBFILE.AAA /nFound version 2 but expected either 3, 4 , or 5. This could be an endian problem.
I was actually having trouble running the real.exe using ds 083.2 for data before 2015, and the p sfc error is popping up even if I correct all vertical level errors. Just cant find the right combination or maby the data must prepared as per the press_pa, hence I am here.

Thank you

Since this is a different issue can you open a new thread? The admins like to keep the issues seperate
 
@ Alfred-Jose

Please note that the utility ./mod_levs.exe only works for intermediate file. Therefore you can use the command as follows:

./mod_levs.exe old-intermediate file new-intermediate file
