The NASA Making Earth System Data Records for Use in Research Environments ([MEaSUREs](https://earthdata.nasa.gov/about/competitive-programs/measures)) Combined Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Moderate Resolution Imaging Spectroradiometer (MODIS) Emissivity for Land (CAMEL) dataset provides monthly emissivity uncertainty at 0.05 degree (~5 kilometer) resolution (CAM5K30UC). CAM5K30UC is an estimation of total emissivity uncertainty comprising three independent components of variability: temporal, spatial, and algorithm. Each measure of uncertainty is provided for all 13 hinge points of emissivity and each latitude-longitude point. Additional details regarding the methodology are available in the User Guide and Algorithm Theoretical Basis Document (ATBD). Corresponding emissivity values can be found in the [CAM5K30EM](https://doi.org/10.5067/MEaSUREs/LSTE/CAM5K30EM.003) data product.Provided in the CAM5K30UC product are layers for algorithm uncertainty, spatial uncertainty, temporal uncertainty, total uncertainty, latitude, longitude, spectral wavelength, CAMEL quality, and total uncertainty quality information.Known Issues* The following granules are missing from the product: January, February, and August of 2000; June and July of 2001; March of 2002; December of 2003; July of 2010; and February of 2016.Improvements/Changes from Previous Version* Version 3 includes new MODIS Terra and Aqua Land Surface Temperature and 3-Band Emissivity (MYD/MOD21) input data in the University of Wisconsin-Madison MODIS Baseline Fit (UWBF) emissivity database and the latest 6.1 version of MODIS Terra and Aqua Land Surface Temperature and Emissivity (MYD/MOD11) and MYD/MOD21 products with the most up-to-date calibration corrections. Additional information on the Version 3 updates is provided in Section 2 of the User Guide and ATBD.
