Radiative cooling, what’s next?

Next Energy, 2023
Radiative coatings make use of omnipresent surface thermal radiation for passive cooling of objects without consuming energy or emitting greenhouse gases, and are a promising energy-saving strategy at scale to address the climate change problem. In the last decade, thanks to advances in photonics and micro/nano-fabrication technologies, we have ...

Vapor condensation with daytime radiative cooling [PDF]

Proceedings of the National Academy of Sciences, 2021
Significance Traditionally, the cooling for passive vapor condensation is mainly provided by convection and conduction. However, these mechanisms do not work when the vapor temperature is near the ambient air temperature. At such temperatures, radiative condensation remains effective.

Atmospheric teleconnection mechanisms of extratropical North Atlantic SST influence on Sahel rainfall [PDF]

, 2014
Extratropical North Atlantic cooling has been tied to droughts over the Sahel in both paleoclimate observations and modeling studies. This study, which uses an atmospheric general circulation model (GCM) coupled to a slab ocean model that simulates this ...

Spectral Emissivity Profiles for Radiative Cooling

ACS Applied Optical Materials, 2023
Passive radiative cooling, an innovative approach for cooling buildings and devices, has attracted considerable attention in recent years. In particular, the spectral emissivity distribution of surfaces plays a crucial role for an object to radiate at wavelengths for which the atmosphere is transparent and solar irradiance is low.

Metamaterial-Based Radiative Cooling: Towards Energy-Free All-Day Cooling

Energies, 2018
In the light of the ever increasing dangers of global warming, the efforts to reduce energy consumption by radiative cooling techniques have been designed, but are inefficient under strong sunlight during the daytime. With the advent of metamaterials and

Radiative Cooling: Principles, Progress, and Potentials

Advanced Science, 2016
The recent progress on radiative cooling reveals its potential for applications in highly efficient passive cooling. This approach utilizes the maximized emission of infrared thermal radiation through the atmospheric window for releasing heat and minimized absorption of incoming atmospheric radiation.

Moisture‐radiative cooling instability [PDF]

Journal of Advances in Modeling Earth Systems, 2016
AbstractRadiative‐convective equilibrium (RCE)—the statistical equilibrium state of the atmosphere where convection and radiation interact in the absence of lateral transport—is widely used as a basic‐state model of the tropical atmosphere. The possibility that RCE may be unstable to development of large‐scale circulation has been raised by recent ...
