[ncl-talk] 3 dimensions to 2 dimensions

[Rick Brownrigg]

HI,

It looks like there may be several problems going here:

i) I speculate you mean something more like this:
  time =f->time
  lat =f->latitude
  lon =f->longitude
  ntim = dimsizes(time)
  nlat = dimsizes(lat)
  nlon = dimsizes(lon)

ii) I'm not sure the intent here:

   Rain(nl,ml) = TRMM(nt,nl,ml)

Each time through the inner loop, it will (re)assign the one by one "nt"
values of TRMM to the same element of Rain(nl, ml), exiting the loop with
it set to the "nt-1"th value. Its equivalent to foregoing the entire inner
loop and just saying Rain(nl,ml) = TRMM(nt-1,nl,ml)

Hope that helps,
Rick
