topcompute_fromreg_imoms3_weigaddr interpolation
Return value
weig, addr: 2D arrays, weig and addr are the weight and addresses used to
perform the interpolation:
dataout = total(weig*datain[addr], 1)
dataout = reform(dataout, jpio, jpjo, /over)

Known issues
Restrictions
- the input grid must be a "regular/rectangular grid", defined as a grid for
which each lontitudes lines have the same latitude and each latitudes columns
have the same longitude.
- We supposed the data are located on a sphere, with a periodicity along
the longitude.
- points located between the first/last 2 lines are interpolated
using a imoms3 interpolation along the longitudinal direction and linear
interpolation along the latitudinal direction
- points located out of the southern and northern boundaries are interpolated
using a imoms3 interpolation only along the longitudinal direction.
