UW-Madison Baseline Fit Emissivity Database

From the University of Wisconsin CIMSS data section: http://cimss.ssec.wisc.edu/iremis/

This global database of infrared land surface emissivity is derived using input from the Moderate Resolution Imaging Spectroradiometer (MODIS) operational land surface emissivity product (MOD11). The baseline fit method (Seemann et al., 2007), based on a conceptual model developed from laboratory measurements of surface emissivity, is applied to fill in the spectral gaps between the six emissivity wavelengths available in MOD11.
