4.3. Input datasets and uncertainties
The MODIS LST products have been validated within 1 K at multiple
sites in relatively wide ranges of surface and atmospheric conditions
(Wan, 2008; Wan, Zhang, et al., 2004). Refinements to the Version 5
LST product have minimized the main sources of uncertainty caused
by cloud contamination and in accurately estimating the surface emissivity,
and significantly improved the accuracy and stability
