summary: | GLAH13 contains sea ice, open ocean, and iceberg elevations corrected for geodetic and atmospheric effects, calculated from algorithms fine-tuned for sea ice returns. Granules contain 14 orbits of data within the sea ice mask. Each GLAH13 file was created from an equivalent GLA13 binary file. The data used to create the GLAH13 values are contained in the equivalent GLAHxx files for the GLAxx files. See the provenance metadata for the creation of the GLA13. |

It is not corrected for saturation effects. If the shot is saturated (satindex above 2) then to correct for saturation the reflectivity estimate needs to be multiplied by the ratio of the corrected energy to the uncorrected energy (sat corrected reflectivity = d_reflctUC * (d_RecNrgAll + d_satNrgCorr)/d_RecNrgAll). The atmospheric corrected reflectivity may be calculated from this uncorrected reflectivity by multiplying it by d_reflCor_atm. d_reflctUC is invalid where d_satNrgCorr is invalid. source: Rel 33 GLAS Binary Data valid_min: 0.0000000000000000 valid_max: 1.0000000000000000 _FillValue: 1.7976931348623157e+308 origname: d_reflctUC fullnamepath: /Data_40HZ/Reflectivity/d_reflctUC coordinates: Data_40HZ_Reflectivity_DS_UTCTime_40 |

Because the saturation corrections are small and data is acquired within 5 deg off nadir, effects on lat and lon can be ignored.

An invalid will be encoded if an optical depth in any of the layers in the 1-second column could not be calculated. This usually occurs in a very optically thick cloud which extinguishes the signal.
