MODIS Daily Black Sky Albedo for Band 6 at 1km Resolution

Black-sky albedo data for MODIS band 6 is produced daily at 30 arc-second (1km) resolution. The dataset covers the entire globe and is generated by LPCLOUD using 16 days of Terra and Aqua MODIS observations, temporally weighted to the ninth day.

Use Cases

• Analyze daily black-sky albedo for MODIS band 6 to model surface reflectance under direct illumination conditions.
• Integrate the 1km resolution albedo layer into global climate simulation grids (CMG).
• Use the band-specific quality flags to filter for highest quality full inversion results in scientific applications.
• Compare black-sky albedo (directional hemispherical reflectance) with white-sky albedo datasets from the same product suite.
• Track changes in surface albedo over time using the daily, temporally-weighted data product.

Strengths

• Daily temporal resolution provides frequent updates.
• Global spatial coverage at 30 arc-second (1km) Climate Modeling Grid (CMG) resolution.
• Product derived from 16 days of Terra and Aqua MODIS data for robust inversion.

Limitations

• Each product file contains only one data layer, requiring multiple files for full spectral analysis.
• Known issues exist, requiring users to consult external assessment websites.
• Data interpretation requires expertise in MODIS products and quality flag usage.
