Yes, sorry but you should not be able to call resmaple()
for a Set whose manifold dimension is less than its
domain dimension. If possible, project your Gridded3DSets
with manifold dimension = 2 and 1 down to a 2 dimensional
domain. For your radar data, perhaps the 2-D domain
(latitude, longitude).
Good luck,
Bill
