DOI: 10.1109/lgrs.2024.3465551
Abstract: Multibeam spaceborne photon-counting laser altimetry obtains multiple tracks simultaneously, enabling coverage of wide areas and various land-cover types. To cope with the rapid denoising of background noise in photon point cloud (PPC), this letter presents… read more here.

DOI: 10.1109/tgrs.2025.3570361
Abstract: Ice, Cloud, and Land Elevation Satellite (ICESat-2) carries the Advanced Topographic Laser Altimeter System (ATLAS), which enhances along-track sampling density but introduces substantial noise in photon point cloud data. Therefore, this study establishes a denoising… read more here.

DOI: 10.1109/tgrs.2025.3631519
Abstract: The Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) provides abundant ocean satellite altimetry data. Photon point clouds data denoised by the official ATL03 algorithm exhibit insufficient continuity, and classical gravity anomaly inversion algorithms suffer from… read more here.
