ATL07 data provides along-track sea surface height and sea ice height measurements from the ICESat-2 satellite. The dataset is produced by the NSIDC from observations by the Advanced Topographic Laser Altimeter System (ATLAS) instrument. Segment lengths vary, with fixed 10-meter segments and heights computed using the DDA-Bifurcation algorithm for strong beams.
Use Cases
- Modeling sea ice freeboard and thickness by analyzing sea_ice_height relative to sea_surface_height.
- Studying ocean surface topography variability from along-track sea_surface_height data.
- Validating altimetry algorithms by comparing heights from standard and DDA-Bifurcation processing.
- Analyzing spatial patterns of sea ice using height data segmented for all beams and strong beams.
Strengths
- Data originates from the Advanced Topographic Laser Altimeter System (ATLAS), a precise spaceborne instrument.
- Provides height calculations using both a standard algorithm and the specialized DDA-Bifurcation algorithm for strong beams.
Limitations
- Specific temporal coverage, spatial resolution, and total record count are not provided.
- Data is segmented into variable lengths, which may complicate consistent spatial analysis without preprocessing.
