The full
Hurricane Isabel dataset
is described
here,
but please note the error in this description. The x,y,z axes are as described, but
the data are given in a permuted order.
If i the denotes the fastest and k the slowest varying parameter, then
the i parameter runs from north to south (negative y direction)
the j parameter runs from west to east (x direction)
the k parameter runs from low to high altitude (z direction).
