Description

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).

Version Description

Changes for Version 6 are as follows:
  • 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
