Pressure level problem

[Yogesh Kumar Tiwari <ktiwari@xxxxxxxxxxxxxxx>]

Dear Ferret users,

I have a file name : - air.2002.nc

and this is having the data like this


name     title                         I         J         K         L
AIR  mean Daily Air temperature       1:144     1:73      1:17    1:365


I am doing like this

yes? let pot=air*(1013/K)^.29
yes? contour pot[x=100,l=1]

Here K is pressure level 1:17 from 1000mb to 10mb

I am geting wrong result in the contour plot.

May be here the K should change first and then multiply with "air" 
because "air" is the matrix like(I,J,K,L) and probably we should make 
the K also in same dimension.

I am seeking help of ferret useres on this.

Thanks in advance

Regards,
Yogesh
