Verticle grid resolution in WRF model.

[G.Sai krishna]

how to know the grid size in z direction. Only number of levels in verticle direction is asked in namelist.input, how to know size of each level.
Whats the difference between e_vert and num_metgrid_levels.

In wrfinput and wrfout files, you can find


float PH(Time, bottom_top_stag, south_north, west_east) ;


PH:FieldType = 104 ;


PH:MemoryOrder = "XYZ" ;


PH:description = "perturbation geopotential" ;


PH:units = "m2 s-2" ;


PH:stagger = "Z" ;


PH:coordinates = "XLONG XLAT XTIME" ;


float PHB(Time, bottom_top_stag, south_north, west_east) ;


PHB:FieldType = 104 ;


PHB:MemoryOrder = "XYZ" ;


PHB:description = "base-state geopotential" ;


PHB:units = "m2 s-2" ;


PHB:stagger = "Z" ;


PHB:coordinates = "XLONG XLAT XTIME" ;

PH + PHB is geopotential at each model level, which can be used to derive the layer depth. Is this what you are looking for?

In the way I know dx, and dy I also want to know dz. where will I find it??
