Re: clmMonTLL function getting error when i calculate arctic oscillation index

Hi Davaa,
If you wish to use clmMonTLL with less than complete years you will need to
copy your array into a new array that has complete years:

; Untested! arr is original array dimensioned time x lat x lon
arr2 =
new((/(2014-1950+1)*12),dimsizes(arr&lat),dimsizes(arr&lon)/),typeof(arr))
arr2!0 = "time"
arr2&time = *yyyymm_time*(1950, 2014, "integer")
arr2!1 = "lat"
arr2&lat = arr&lat
arr2!2 = "lon"
arr2&lon = arr&lon
copy_VarAtts(arr,arr2)
arr2({:201404},:,:) = (/ arr /)
delete(arr)

Hope that helps. If you have any further questions please respond to the
ncl-talk email list only.
Adam
