This data set (ATL13) contains along-track water surface heights and descriptive statistics for inland water bodies. Water bodies include lakes, reservoirs, bays, and estuaries. Descriptive statistics include along-track surface slope (where data permit), mean and standard deviation, subsurface signal (532 nm) attenuation, wave height, and coarse depth to bottom topography.

The number of short segments to be designated as anomalous, due to near-shore influences, is implemented as a 9x9 matrix that depends on water body type and size; Cloud confidence flag parameters are now retrieved from the ATL09 product and reported on ATL13 at the short segment rate; Implemented surface temperature and NOAA snow/ice flag at the short segment rate; Added six water body transect parameters.NSIDCMinor VersionNSIDCSpatial Reference SystemsEPSG:4326WGS 84NSIDCLevel of ServiceNo Data AccessNSIDCFull Dataset CitationJasinski, M.
