[gradsusr] the calculation of stream function from 1000 10 hPa level

[resmi ea]

Dear users
i would like to calculate the stream function from 1000-10 hPa levels. I am
using NCEP/NCAR reanalysis data. i have tried this commands and it works on
single level.

'reinit'
'sdfopen H:\windows\ncep\uwnd\uwnd.2009.nc'
'sdfopen H:\windows\ncep\uwnd\vwnd.2009.nc'
'set lat -90 90'
'set lon 0 360 '
'set lev 1000'
'set time 23jan2009'
'set mproj scaled'
'set parea 1 10.4 1.5 7.6'
'define vor1=hcurl(uwnd,vwnd.2)'
'define psi= fish(vor1)'
*'d psi'
'define psii=psi-aave(psi,global)'
'set gxout shaded'
'd psii/1e7'

Regards
