Global Snow-Free Albedo Maps from MODIS for 2002

2002 data provides snow-free, spatially complete 16-day global albedo maps derived from MODIS Collection 4 products. The dataset contains 9 files with black-sky and white-sky albedos for 7 spectral and 3 broad bands, using an ecosystem-dependent interpolation to fill gaps. It is produced by the National Aeronautics and Space Administration.

Use Cases

• Modeling surface energy balance using black-sky and white-sky albedo values.
• Analyzing seasonal land surface reflectance changes across 7 spectral bands.
• Validating other remote sensing albedo products with the provided quality information.
• Studying ecosystem-dependent albedo patterns with the interpolated, gap-filled data.

Strengths

• Provides data for a full year (2002) with 16-day temporal resolution.
• Uses an ecosystem-dependent interpolation technique to create spatially complete, snow-free maps.
• Contains albedo values for 7 spectral bands and 3 broad bands.

Limitations

• Conflicting last updated dates: datagov lists 2026-03-13, while nasa_earthdata lists 2002-12 31.
• Specific row counts, file sizes, and column names are not provided by any source.
