Daily Lake Ice Phenology Time Series from AMSR Satellites

Satellite-derived daily lake ice phenology data provides ice-on and ice-off retrievals for large lakes across the Northern Hemisphere. The dataset is produced by the National Aeronautics and Space Administration using 5 km resolution data from the AMSR-E and AMSR2 sensors. It supports regional monitoring and global change studies.

Use Cases

• Monitoring seasonal ice coverage trends for climate change impact studies using daily ice-on/ice-off retrievals.
• Regional assessment of lake ice phenology across the Northern Hemisphere using the 5 km EASE-Grid 2.0.
• Validating and improving lake ice models with satellite-based observational time series data.

Strengths

• Provides daily, hemisphere-wide coverage for large lakes using a consistent 5 km EASE-Grid 2.0.
• Derived from established satellite instruments (AMSR-E and AMSR2), supporting long-term analysis.
• Cross-platform presence on data.gov and NASA EarthData indicates recognized importance for scientific use.

Limitations

• Key technical details like row count, file size, and specific column names are unavailable from all sources.
• There is a conflict in the 'last updated' metadata, with dates ranging from 2022-12-31 to 2026-03-13.
• The license is ambiguously listed as 'other-license-specified' without clear terms.
