WebEmissivities that are derived using temperatures from AST_08 and ASTER thermal surface radiances from AST_09T perform similar or worse when compared with OSTES emissivities. Emissivities delivered by AST_05 also exhibit step discontinuities, whereas the OSTES emissivitites are smoother over homogeneous surfaces. WebThe temperature and emissivity separation is complex due to the existing non-linear relation between the temperature and radiance (Li et al., 1999; Collins et al., 2001). The radiance can be calculated using the Planck’s function and target emissivity (for a given wavelength and temperature).
