Average wind speed at sigma level

[Leopoldo Alvarez]

Dear grads-users,

I am using this procedure to paint the average wind speed about 10m.

'tg1=ave(mag(u10,v10),t=2,t=9)'
'set gxout shaded'

'd tg1'

How can I determine the average wind speed at sigma level or pressure
level?. For example to 0=0.97 (sigma) and presion=850 (mb).

Thanks in advance
Leopoldo Alvarez
