upper_bc_init error

[ummed singh]

Dear Dr Gabriele, 

I am working with V4.3 with single domain and found error in upper boundary setting with chem=202, 

The error was following 

" call upper boundary initialization

 upper_bc_init: intializing domain 01
upper_bc_init: input filename not specified in namelist
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0 " 

I have already set these parameters in namelist 

 have_bcs_chem                       = .true., .true.,           
 have_bcs_upper                      = .true., .false., .false., 
 fixed_ubc_inname                    ="ubvals_b40.20th.track1_1996-2005.nc",

Then, how do we fix "upper_bc_init" parameters in namelist.input? means in pressure level (50mb) or other terms.   

With regards

aryan

Dear Aryan

our website as well as the WRF-Chem User Guide (page 34) include detailed instructions on how to run WRF-Chem with upper boundary conditions and I suggest you take a look at these for more information. Also make sure that all the necessary input files (the file you reference above as well as the file clim_p_trop.nc, which includes a climatology for tropopause levels) are in your run directory.

hi ANIE

Please share your error message then I will suggest you. 

With regards

the run stops without any error. 
stops  at "aerosols_driver calling mosaic_aerchem_driver. 

                          mosaic_aerchem_driver: back from aerchemistry." without kpp

and  at "kpp_mechanism_driver: calling mozart_mosaic_4bin_aq_interface" with kpp on

hi ANIE

It's related to compilation. you need to compile wrf with KPP if you are using chem_opt=202. 

best wish
