MYD11C3: Monthly Land Surface Temperature and Emissivity Grid

The MYD11C3 Version 6 product provides monthly Land Surface Temperature and Emissivity (LST&E) values in a 0.05-degree (5,600 meters) Climate Modeling Grid (CMG) covering the entire globe with 7,200 columns and 3,600 rows. It is derived by compositing and averaging daily observations from the MODIS/Aqua satellite and includes layers for daytime and nighttime LSTs, quality control, observation times, view zenith angles, and emissivities from six spectral bands. This dataset was decommissioned on July 31, 2023, and users are directed to use the updated Version 6.1.

Use Cases

• Monitoring global land surface temperature trends based on monthly averaged satellite observations.
• Analyzing surface emissivity variations across different land cover types using data from six spectral bands.
• Assessing data quality for climate models using the provided quality control assessments and clear-sky observation counts.
• Studying diurnal temperature cycles by comparing daytime and nighttime LST layers.

Strengths

• Provides global coverage with a consistent 0.05-degree grid resolution (7,200 x 3,600 cells).
• Includes multiple derived layers for both daytime and nighttime observations, such as LST, quality control, and emissivity.
• Algorithm improvements in Version 6 removed cloud-contaminated LSTs and updated emissivity coefficients.

Limitations

• The dataset is deprecated; Version 6 was decommissioned on July 31, 2023.
• Specific column names and exact row/file size are not provided in the available metadata.
• Known issues exist, requiring users to consult an external quality assessment website.
