Data for: Daytime passive radiative cooler using porous alumina

These datasheets include theoretical and experimental data ploted in the manuscript. Sheet 1 gives dielectric constants for Al2O3 and AAO. Sheet 2 describes absorptivity/emissivity of AAO with filling factor and incident angle varies. Sheet 3 lists solar spectrum, atmosperic window transmittance and measured absorption/emittance of AAO from visible to far-infared wave. Sheet 4 is the theoretical cooling power calculated with different nonradiative coefficient. Sheet 5 shows measured cooling performance of AAO sample in 24h.
