-Caselles et al. (1997) gives reference, in Table 3 and Figure 2, to both the NDVI range used (0.15 - 0.71) and the corresponding emissivity range used (0.97 - 0.99).

-The emissivity is the efficiency of longwave energy returning to the atmosphere from the skin surface. The skin surface receives heat from the thermal infrared radiation of the Sun, through atmospheric interaction. A part is returned to the atmosphere fast, and another part is kept in the surface skin to be returned later. In more scientific terms, the grey body radiation is equal to the black body radiation times the emissivity.
