Aqua MODIS Land Surface Temperature Daily Global Data

The Aqua MODIS MYD11C1 Version 6.1 product provides daily Land Surface Temperature and Emissivity values on a global 0.05-degree Climate Modeling Grid. The dataset includes daytime and nighttime observations, quality assessments, view angles, and emissivity from specific spectral bands. It is produced by NASA and derived from the MYD11B1 product.

Use Cases

• Modeling global climate patterns based on daily land surface temperature grids.
• Analyzing diurnal temperature variations based on separate daytime and nighttime observations.
• Assessing surface emissivity for specific spectral bands (20, 22, 23, 29, 31, 32) mentioned in the description.
• Evaluating land surface thermal properties using quality control assessments and view zenith angles.

Strengths

• Provides daily global coverage on a consistent 0.05-degree grid.
• Includes separate layers for daytime and nighttime observations.
• Derived from the calibrated MYD11B1 product with documented improvements in Version 6.1.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Known issues exist, requiring consultation of the external MODIS/VIIRS Land Quality Assessment website.
