Description

ATL13QL is the quick look version of ATL13. Once final ATL13 files are available the corresponding ATL13QL files will be removed. ATL13 contains along-track surface water products for inland water bodies. Inland water bodies include lakes, reservoirs, rivers, bays, estuaries and a 7 km 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
