title GLAS/ICESat L1A Global Engineering Data (HDF5)
comment The level 1A global engineering data (GLAH03) data granules contain approximately 190 minutes (2 orbits) of GLAS instrument housekeeping data including temperatures, voltages, and currents.
summary GLAH03 contains the instrument engineering data and is a time-ordered level 1A data product. The data has been converted from the raw form to engineering units. The data was used to calibrate measurements contained on GLAH01 and GLAH02 and to perform GLAS instrument performance assessment. Each GLAH03 file was created from an equivalent GLA03 binary formatted file. The provenance metadata shows the history that created the GLA03.

seconds The transmit time of the first shot in the 1 second frame measured as 'UTC seconds' elapsed since Jan 1 2000 12:00:00 UTC. This time has been derived from the GPS time accounting for leap seconds. The first item is the whole number of seconds; the second item is the fractional part in microseconds.

SuggestedUsage GLAH03 contains the instrument engineering data and is a time-ordered level 1A data product. The data has been converted from the raw form to engineering units. The data was used to calibrate measurements contained on GLAH01 and GLAH02 and to perform GLAS instrument performance assessment. Each GLAH03 file was created from an equivalent GLA03 binary formatted file. The provenance metadata shows the history that created the GLA03.
