This phenomenon is called radiational cooling and here on the First Coast, ... If there are clouds present, that longwave radiation will stay close to the ground modifying temperatures.

Clouds approximately double the reflection of shortwave radiation back to space (i.e. a cooling) and redirect about 20% more ... radiation channel and a total radiation channel. The longwave radiation ...

There was a wide range of temperatures early this morning across eastern Iowa. Looking at the map below, you can see temperatures were in the 60s across southern portions of the KWWL Viewing area ...

Yet radiative cooling has rarely been discussed as a potential tool for climate action, Raman said. Most researchers saw the phenomenon as an interesting physical fact with few practical applications.

More intriguingly, it emits heat in the form of longwave infrared radiation into the icy universe, ... A solution-processed radiative cooling glass. Science, 2023; 382 (6671): ...

Unlike previous attempts at cooling coatings, the new UMD-developed glass is environmentally stable—able to withstand exposure to water, ultraviolet radiation, dirt and even flames, enduring ...
