摘要：

Light detection and ranging (LIDAR) data acquired during the AMSR-Ice03 Arctic flights are used to observe and characterize the spectral behavior of sea ice roughness. Height distributions and roughness spectral densities are derived from surface profiles measured over a variety of sea ice types. The spectral densities are fit to Lorentzian curves to obtain the correlation length and root-mean-square height of roughness within the sampling bandpass of the LIDAR profiler. The utilization of these spectral parameters outside of their bandpass is also discussed.
