[ncl-talk] summing each of three time-series values

[sangeeta maharjan]

hi,

I am planning to use following codes in my scripts to meet my requirements
that i have mentioned in former email.
------------------------------------------------------------------------------------------------------------------------------------------------

W     = wrf_user_getvar(f,"wa", -1)

dim_w=dimsizes(W)

W1 = new((/dim_w(1),dim_w(2),dim_w(3)/),float

W2 = new((/dim_w(1),dim_w(2),dim_w(3)/),float)

W3 = new((/dim_w(1),dim_w(2),dim_w(3)/),float)

MEAN_W = new((/dim_w(0)-4,dim_w(1),dim_w(2),dim_w(3)/),float)

 do n=0,dim_w(0)-5

   W1(:,:,:)=W(n,:,:,:)
   W2(:,:,:)=W(n+1,:,:,:)
   W3(:,:,:)=W(n+2,:,:,:)

  MEAN_W(n,:,:,:)=(W1+W2+W3)/3

 end do

-------------------------------------------------------------------------

I suppose these will be fine.


Regards,

Sangeeta Maharjan.
