GLAH15_034

GLAS/ICESat L2 Ocean Altimetry Data (HDF5) V034

Version 034
  • Abstract
    GLAH15 contains the ocean elevation and small-scale roughness corrected for geodetic and atmospheric affects, calculated from algorithms fine-tuned for ocean returns. Data granules will contain 14 orbits of data over the oceans.
  • Purpose
    GLAH15 contains ocean elevation and small-scale roughness data for researchers. Includes the geolocation, reflectance, and the geodetic, instrument, and atmospheric corrections. Parameters are at the full 40Hz resolution within the ICESat ocean mask. Each GLAH15 file was created from an equivalent GLA15 binary file. The data used to create the GLAH15 values are contained in the equivalent GLAHxx files for the GLAxx files. See the provenance metadata for the creation of the GLA15.
  • Version Description
    GLASHDF V2.0-Elevations for all products except GLAH14 are now based on the range from the Gaussian fit to the transmit pulse to the Gaussian fit to the received echo. Range used for trop corrections was changed from threshold to centroid.(See Rel Notes)
