title	GLAS/ICESat L2 Global Aerosol Vertical Structure Data (HDF5)
comment	The level 2 aerosol vertical structure data contains cloud and aerosol backscatter and extinction cross section profiles provided at a minimum of once per 4 seconds. Data granules will contain approximately 23 hours (14 orbits) of data.
summary	GLAH10 contains cloud and aerosol backscatter and the extinction cross section data for researchers. Cloud data are provided at 1Hz and aerosol data will be provided at .25Hz. Each GLAH10 file was created from an equivalent GLA10 binary file. The data used to create the GLAH10 values are contained in the equivalent GLAHxx files for the GLAxx files. See the provenance metadata for the creation of the GLA10.

SuggestedUsage	GLAH10 contains cloud and aerosol backscatter and the extinction cross section data for researchers. Cloud data are provided at 1Hz and aerosol data will be provided at .25Hz. Each GLAH10 file was created from an equivalent GLA10 binary file. The data used to create the GLAH10 values are contained in the equivalent GLAHxx files for the GLAxx files. See the provenance metadata for the creation of the GLA10.
