Mapping Nighttime and All-Day Radiative Cooling Potential in Europe and the Influence of Solar Reflectivity

open access: yesAtmosphere, 2021
Radiative cooling is a natural process to cool down surfaces through the rejection of thermal radiation using the outer space as a cold sink, taking advantage of the transparency of the atmospheric windows (8–14 μm), which partially matches the infrared ...
