Global Daily Black Sky Albedo for MODIS Band 1

LPCLOUD produces daily global black-sky albedo data for MODIS band 1 at 30 arc-second resolution. The dataset is generated using 16 days of Terra and Aqua MODIS observations, temporally weighted to the ninth day. It is designed for climate simulation models.

Use Cases

• Model surface reflectance in climate simulations using the black-sky albedo layer for MODIS band 1.
• Assess daily albedo variability for land surface studies using the temporally weighted daily product.
• Filter data quality for scientific applications using the band-specific quality flags described in the user guide.
• Compare albedo across spectral bands by referencing the suite of 10 black-sky and 10 white-sky albedo layers.

Strengths

• Daily global coverage at 30 arc-second (approximately 1km) resolution.
• Product derived from 16 days of Terra and Aqua MODIS data for stability.

Limitations

• Each product file contains only one data layer, requiring multiple files for full analysis.
• Known issues exist, requiring consultation of external quality assessment websites.
• Specific row counts, column details, and sample data are unavailable for assessment.
