Northern Hemisphere Daily Sea Ice Extent with Multisensor Analysis

MASIE-NH provides daily measurements of sea ice extent and edge boundaries for the Northern Hemisphere and 16 specific Arctic regions. The dataset is derived from U.S. National Ice Center (USNIC) source data and is presented in polar stereographic projections at 1 km and 4 km grid resolutions. It includes numeric extent values, time series plots, and image files for visual analysis.

Use Cases

• Analyzing daily sea ice extent trends for 16 defined Arctic regions using the provided square kilometer values.
• Mapping the visual sea ice edge boundary from image files in polar stereographic projection.
• Creating time series models of ice growth and melt using the consistent daily measurements.
• Comparing multisensor analyzed ice data with other satellite-derived products for validation studies.
• Assessing regional ice coverage changes in specific areas like the Beaufort Sea or Baffin Bay.

Strengths

• Provides data for 16 distinct Arctic regions, enabling detailed regional analysis.
• Offers dual spatial resolutions (1 km and 4 km grid cells) for different analytical needs.
• Includes multiple data products: numeric extent files, time series plots, and visual image files.
• Derived from operational U.S. National Ice Center (USNIC) data, a recognized authoritative source.

Limitations

• Specific row counts, column names, and total dataset size are not provided by any source.
• Sources conflict on license details: datagov specifies 'other-license-specified', while nasa_earthdata lists 'None'.
• The intended uses differ from other NSIDC sea ice products, requiring careful review of documentation.
