[Wrf-users] vertical velocity

Hello Cory,

I believe the variable "W" in the wrfout netcdf files is the true vertical velocity component, that is, dz/dt expressed in m/s, where z is the height in meters. Running 'ncdump -h [netcdf file]' will display all the variables in the file along with their dimensions and units.

Best regards,

To all: 

Dumb question....The vertical velocity in the raw .nc output file...Is that the vertical velocity w/r/t the sloping sigma surface?
