Version Summary

Modified the computations of the deconvolution of subsurface backscatter profile and deconvolution of surface water profile; Expanded iteration range of subsurface parameters within deconvolution scheme and added quality flags; Added surface quality flags; Defined end of partial short segments as the final signal photon; To avoid inadvertently capturing subsurface photons associated with bottom reflection and machine error, such photons are further screened and removed from processing using a mirroring approach applied to the water surface; Replaced “crossing-number” algorithm with “winding number” algorithm for better determination of ICESat-2 transects within the inland water mask shapes.

Overview

This data set (ATL13) contains along-track surface water products for inland water bodies. Inland water bodies include lakes, reservoirs, rivers, bays, estuaries and a 7km near-shore buffer. Principal data products include the along-track water surface height and standard deviation, subsurface signal (532 nm) attenuation, significant wave height, wind speed, and coarse depth to bottom topography (where data permit).
