Figure 1 | Explanation and validation of the effect of haze on radiative cooling. (a-b), Schematic of passive daytime radiative cooling (PDRC) under clear and haze-polluted skies. Particulate matter (PM) in a haze-polluted atmosphere scatters both sunlight and infrared thermal radiation from the radiative cooler. While the former is beneficial, the latter is detrimental to PDRC. (c), Solar spectrum and atmospheric transmittance at various haze concentrations, indicated with various PM2.5. With the increase of PM2.5, the attenuation of solar radiation is more significant than that of atmospheric transmittance. This selective scattering is the basis of the analysis in this work.
