Re: Transform 3d 2 2d variable

Vanesa,

You either need to only request one time step:

> hr = wrf_user_getvar(a,"rh",0) ; relative humidity at first time step

 or else subscript "hr" accordingly before you call gsn_csm_xy. You didn't include the code for how you are trying to call gsn_csm_xy, so this is just a guess:

   plot = gsm_csm_xy(wks,x,hr(0,:,:),res) ; plot only first time step

You can also interpolate a 3D to a 2D variable using an input plane. See wrf_user_intrp3d:
