Global monthly mean climatology of surface emissivity derived from multiple satellite products. The dataset provides broadband thermal infrared emissivity, 10.5-micron emissivity, and microwave emissivities at four frequencies and two polarizations. It was produced by the GES DISC and last updated in 2007.
Use Cases
- Validate modeled broadband thermal IR emissivity fields against the ISCCP FD product data.
- Analyze spatial patterns of 10.5-micron emissivity from the ISCCP IREMISS product for surface type classification.
- Incorporate microwave emissivity values at four frequencies and two polarizations from SSM/I into land surface assimilation systems.
- Study the climatological mean and standard deviation of emissivity on a 1.0-degree-equivalent equal-area grid.
Strengths
- Climatology provides stable monthly means and standard deviations for model initialization.
- Combines emissivity data from multiple established satellite products (ISCCP FD, IREMISS, SSM/I).
- Global spatial coverage on a consistent 1.0-degree-equivalent equal-area grid.
Limitations
- Data is a static climatology last updated in 2007 and does not represent recent conditions.
- Specific row count, file size, and sample resolution details are unavailable.
- As an ancillary product, it may lack the raw observational data used for its creation.
