Calipso Data - how can I get the height?

Hi NCL users,

I got the calipso data and I'm trying to plot of
Total_Attenuated_Backscatter_532 in a xy-plot. I intend to do just an
average of the 50 lat/lon.

How can I get the height of the data? Because I don't have a var named
"height" as the "latitude" and "longitude".

My script is below:
--------------------------------------------------------------------------------------------------------------
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"

calipsofile =
addfile("CAL_LID_L1-ValStage1-V3-01.2011-05-01T05-00-22ZN.hdf","r")
tab = calipsofile->$"Total_Attenuated_Backscatter_532"$
printVarSummary(tab)

avgtab = dim_avg(tab(fakeDim41|1:582, fakeDim40|1:50))

wks = gsn_open_wks( "pdf", "graficos_calipso_mean" )

res = True
res@trYReverse = True
res@trXMinF = 0.

grafico1 = gsn_xy( wks, avgtab(:), ispan(1,582,1), res )
--------------------------------------------------------------------------------------------------------------

Someone could help me?
