[ncl-talk] Converting hybrid sigma-pressure coordinate to pressure level

[Dennis Shea]

eg:

;***************************************************
; interpolate to pressure levels
;***************************************************
 plevs =
(/1000,990,980,965,950,930,900,870,840,800,750,700,600,500,400,200/)
 fake = sigma   ; hyb
 fake = 0          ; hya

data_plevs = vinth2p(data ,fake ,sigma ,plevs ,ps*100 ,1,1000,1,True)
printVarSummary(data_plevs)
