We develop a framework for retrieving the 30 m BBE from Landsat surface reflectance data to estimate SRBs at finer scales and validate coarse resolution data. In the developed framework, the land surface is ...
WebDec 23, 2016 · The emissivity peak at 4200 nm is due to the absorption lines of the CO 2 in the surrounding air. Note that the increase in the emissivity at wavelengths greater than 4800 nm is due to the 1000-nm-thick SiO 2 layer supporting the Si rods (see the SiO 2 absorption spectrum in fig. S2).
