Land surface temperature (LST) and land surface emissivity (LSE) are two critical parameters in the physics of land surface processes at different scales. In this paper, an improved linear spectral emissivity constraint method is proposed to make the retrieved emissivity spectra be continuous at the adjacent segments. To evaluate the proposed method, simulation data covering various land surface and...
Land surface temperature (LST) is required by a series of surface studies and usually estimated using thermal infrared remote sensing data. In this paper, we propose a method to retrieve LST for MODIS data using its mid-infrared bands 22 and 23. As the central wavelengths of bands 22 and 23 are quite close, we assume that (1) band-averaged surface e-missivities are equal in these two bands, and (2)...
Separation of land surface temperature (LST) and emissivity from the remote sensing data is crucial to the urban energy consumption estimation. The difficulty of the TES method is that a single multispectral thermal measurement with N bands presents N equations with N+1 unknown parameters (N spectral emissivities and one land surface temperature).Accordingly, the simultaneous estimation is an underdetermined...
