Abstract: Data granules contain approximately 23 minutes (1/4 orbit) of data and will include pulse travel times, the transmitted and received waveform, transmitted and received energy, echo time offsets, and instrument filter and threshold values.
Purpose: Instrument scientists can use this to check the health and welfare. The waveforms are useful for altimetric scientists studying detailed surface characteristics that cannot be fully expressed in the waveform parameterization on GLA05, especially over ice sheets and land. The product is required for testing algorithms for calculating surface elevations and characteristics from the waveforms during validation and as the instrument ages. This is used as input for GLA05.
