How to output deposition velocity for chemicals

[Luyikeka]

Hi everyone,

I came across a question about outputing variables, deposition velocity for chemicals. It gave following warning information:

W A R N I N G : Unable to modify mask for dvel_o3. Variable not found. File: all_ozone_chemical_physics.txt at line 12
W A R N I N G : Unable to modify mask for ddmass_o3. Variable not found. File: all_ozone_chemical_physics.txt at line 12
W A R N I N G : Unable to modify mask for ddmass_o3. Variable not found. File: all_ozone_chemical_physics.txt at line 12


I failed to output the variables of deposition velocity of ozone.
I edited namelist.inp file, and added:

&time_control
iofields_filename = "all_ozone_chemical_physics.txt",

&chem
chemdiag = 1,1,1,
diagnostic_dep = 1,

And I used a file including the variables I want to output, in the path same as namelist.inp:
+:h:0:conv_co,conv_o3,chem_o3,vmix_o3,advh_o3,advz_o3,dvel_o3,ddmass_o3

And I'm using the wrfchem version 4.1.2. My namelist.inp, and i/o file are attached.

Best regard,
Luyi
