MODIS/Aqua Thermal Bands: Daily Global 1km Satellite Data

MYDTBGA Version 6 provides daily global brightness temperature and albedo data at a 1-kilometer pixel resolution from the Aqua satellite's MODIS instrument. The product, now decommissioned as of July 31, 2023, was produced by the National Aeronautics and Space Administration (NASA). It uses a 'best available pixel' algorithm stored in HDF files.

Use Cases

• Modeling land surface temperature based on brightness temperature data from bands 31 and 32.
• Analyzing daily thermal anomalies or trends using the 1km resolution global coverage.
• Studying surface albedo properties in thermal infrared wavelengths based on band 20 data.
• Investigating the 'best available pixel' selection algorithm for multi-observation compositing.

Strengths

• Provides daily global coverage at a consistent 1-kilometer pixel resolution.
• Includes data from specific, well-defined MODIS thermal bands (20, 31, 32).
• Product version and decommission date are explicitly stated, providing clear version history.

Limitations

• The dataset was decommissioned on July 31, 2023, limiting its use for current monitoring.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
