WebThe accuracy of the LST estimated by Equation (4) depends on the accuracy of the upwelling and downwelling radiation and the broadband emissivity. The accuracy of the pyrgeometer is claimed to be about 9 W·m −2 . The broadband emissivity matches well the ground measurements, with a standard deviation of 0.0085 and a bias of 0.0015 . WebEmissivity is mathematically defined as the ratio of the thermal radiation from the surface to the radiation from an ideal black surface at the same temperature; the value varies from …

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).
