ICECAP Lidar Raw Time-of-Flight Measurements for Polar Ice Sheets

IceBridge Sigma Space Lidar L0 Raw Time-of-Flight Data, Version 1 contains raw time-of-flight measurements for Antarctica and Greenland acquired by the Sigma Space Lidar. The data were collected by scientists working on the NSF and NERC-funded ICECAP project, with additional support from NASA Operation IceBridge. The dataset is available in BIN, HTML, and ISO formats.

Use Cases

• Calibrating and validating processed lidar elevation models using raw time-of-flight signals.
• Studying surface characteristics and roughness of the Antarctic and Greenland ice sheets.
• Supporting the ICECAP project's investigation into the cryospheric evolution of the Central Antarctic Plate.
• Analyzing sensor performance and raw data characteristics from the Sigma Space Lidar instrument.

Strengths

• Data covers two major ice sheets, Antarctica and Greenland, providing broad polar coverage.
• Collected under the multi-agency ICECAP project, funded by NSF, NERC, and NASA, indicating institutional support.

Limitations

• Column names and dataset size (row/record count) are unknown across all sources.
• Sources conflict on the last updated date, reporting both 2011-12-23 and 2026-03 13.
