thermal radiation

In 2021 a collaborative of scientists published a report that identified the immediate effects of an asteroid, including “shock waves that can knock down forests and buildings, thermal radiation that can set fire to surrounding environment and tsunami waves for impacts in the ocean.”

When heated, the base layers accumulate thermal radiation, which can be thought of as a bath of photons.

A micrometer-thick silicon polymer was added to enhance the structure's cooling power by reflecting thermal radiation through the atmospheric window and into outer space.

This technique can be used to detect both the thermal radiation of the planet, as the team has done to detect the planet candidate, and specific emission lines associated with material falling onto the planet and hitting its surface with high velocity.

The team coated the roofs, walls, and road pavements of an industrial area in Singapore and found that by comparison with an adjacent uncoated area, the coated environment was up to two degrees Celsius cooler in the afternoon, with pedestrian thermal comfort level improving by up to 1.5 degrees Celsius, measured using the Universal Thermal Climate Index -- a common international standard for human outdoor temperature sensation that takes into account temperature, relative humidity, thermal radiation, and wind speed.
