[Wrf-users] WRF height variables question

[Irina Rypina]

Hi,

I am trying to use WRF output (from a wrfout* file) and have a  
question about WRF variables.

For my analysis, I only need to know the 3 components of air  
velocities, u,v and w, and their corresponding grids in 3d (lat, lon,  
height above sea level) and time.

I believe "U", "V", and "W" variables in WRF give the 3 components of  
velocity, and I think the lateral lat and long grids for these are  
given by "XLONG_U,XLATG_U", "XLONG_V,XLATG_V", and "XLONG,XLATG."

I also found the time variable "XTIME" that gives time stamps for "U",  
"V", and "W."

But what I cannot find are the z-grids (height above sea level in  
meters) at which "U", "V", and "W" are given.

Can anyone please help me with this?

Thanks!
Irina
