MASAM2: Daily 4 km Arctic Sea Ice Concentration

July 2012 to present, this prototype dataset provides daily 4 km sea ice concentration for the Arctic. It is a blended product combining ice coverage from the Multisensor Analyzed Sea Ice Extent (MASIE) product with ice concentration from the Advanced Microwave Scanning Radiometer 2 (AMSR2). The data was developed to provide greater accuracy and higher resolution for initializing operational sea ice forecast models.

Use Cases

• Initializing operational sea ice forecast models based on the blended concentration product.
• Analyzing daily changes in Arctic sea ice extent and concentration based on the 4 km grid.
• Comparing blended satellite-derived ice concentration against single-source products.
• Studying long-term trends in Arctic sea ice from July 2012 onward.

Strengths

• Blends two established data sources (MASIE and AMSR2) for potentially greater accuracy.
• Provides high-resolution data at a 4 km grid cell size.
• Offers a long temporal record covering from July 2012 to the present.

Limitations

• Metadata completeness is low; specific column names, row counts, and file sizes are not provided on any platform.
• The dataset is labeled as a prototype, which may imply it is an experimental or non-operational product.
• License information is inconsistently reported as 'other-license-specified' on some platforms and 'None' on others.
