Researchers at the Norwegian Life Sciences University are providing lidar data consisting of overlapping swaths, where measurements taken at the maximum (20 deg) angle of one swath are duplicated closer to nadir in another swath.  The presumption is that the near-nadir measurements are more accurate and will allow a comparison to evaluate the error in the off-nadir values.  They are mostly interested, however, in how those errors affect errors in the resultant biomass estimates.
