Combined ASTER and MODIS Emissivity database over Land (CAMEL) Covariances Climatology Monthly Global 0.25Deg V003
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/measures/lste/cam5k30covclim.003
Description
The NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Combined Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Moderate Resolution Imaging Spectroradiometer (MODIS) Emissivity for Land (CAMEL) data suite has been expanded to include a monthly global covariances climatology product (CAM5K30COVCLIM).
The product is provided at 0.25 degree (~25 kilometer) resolution. The CAMEL covariance product includes the mean and variance of the covariance matrixes created for each month from 2003 through 2021 (19 years) on a 0.25 x 0.25 degree grid of 416 spectral points from the V003 CAMEL Emissivity product (CAM5K30EM). Additional details regarding the methodology are available in the User Guide and Algorithm Theoretical Basis Document (ATBD).

Provided in the CAM5K30COVCLIM product are variables for the mean and variance of the emissivity, latitude, longitude, spectral frequencies, and number of observations.
