CAMEL: Monthly Global Land Emissivity Climatology, 2003-2021

NASA's MEaSUREs CAMEL data suite includes a monthly global emissivity climatology product at 0.05 degree (~5 kilometer) resolution. The CAM5K30EMCLIM product represents the mean emissivity from 2003 through 2021, spanning 19 years. Variables include latitude, longitude, wavelength, sample count, quality flags, snow fraction, and emissivity.

Use Cases

• Modeling surface energy balance and longwave radiation based on global emissivity data.
• Analyzing seasonal and interannual variability in land surface properties based on the 19-year monthly climatology.
• Improving atmospheric correction for thermal infrared satellite data based on emissivity values.
• Studying snow cover dynamics and its impact on surface emissivity based on the included MODIS snow fraction.

Strengths

• Data represents a 19-year climatology from 2003 through 2021, providing a long-term baseline.
• Product combines measurements from two established satellite instruments, ASTER and MODIS.
• Spatial resolution is 0.05 degrees, approximately 5 kilometers.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
