MI3DLSNF_002: Daily Global Land Surface and Vegetation Summary

MI3DLSNF_002 is a daily global summary of land surface and vegetation parameters derived from the Multi-angle Imaging SpectroRadiometer (MISR) instrument. The dataset provides a daily statistical summary of directional hemispherical reflectance (DHR), fractional absorbed photosynthetically active radiation (FPAR), DHR-based normalized difference vegetation index (NDVI), and land surface bidirectional reflectance factor (BRF) model parameters, classified into six vegetated and one non-vegetated type. Data is reported on a geographic grid with a resolution of 0.5 degrees by 0.5 degrees.

Use Cases

• Monitoring global vegetation health and phenology based on daily DHR-based NDVI and FPAR summaries.
• Modeling land surface bidirectional reflectance for atmospheric correction studies using the BRF model parameters.
• Analyzing spatial patterns of absorbed photosynthetic radiation for ecological and agricultural research.
• Studying surface reflectance anisotropy and albedo using multi-angle DHR data from nine camera views.

Strengths

• Provides multi-angle observations from nine cameras with view angles at 0, 26.1, 45.6, 60.0, and 70.5 degrees.
• Offers global coverage with a consistent 0.5-degree geographic grid resolution.
• Contains a specific classification scheme with six vegetated and one non-vegetated land cover type.

Limitations

• Metadata completeness is medium; specific column names, row counts, and file sizes are not provided across platforms.
• The 'FIRSTLOOK' processing uses climatology from the previous year and cannot be generated until the end of the month, limiting real-time analysis.
• Platforms list conflicting or incomplete license information (e.g., 'other-license-specified' vs. null).
