The view of Earth from space is famously familiar—bright blue ocean, swirling gyres of white clouds, touches of terrestrial green. The luminosity of this image is the result of the sun’s rays shining ...

Two weeks ago, I talked about an introduction to radar and how it works on a basic level. This time, we are looking into radar reflectivity specifically, the most popular product of weather radar.

Since May 24, 2019, SpaceX has been launching satellites into orbit 60 at a time to bolster the ranks of its Starlink megaconstellation – a fleet of networked sats flying in formation that, once ...

Engineers have found a way to make liquid metals switch between reflective surfaces or those that scatter light. The transition only requires a small zap of electricity and could be used to make ...

Earth’s climate is being changed substantially by a buildup of atmospheric greenhouse gases, but a group of leading climate scientists contends the overall impact is not understood as well as it ...

An international research team has demonstrated how conventional radiative cooling coatings can be optimized to further reduce building surface temperatures, cutting energy consumption, while also ...

Hot and arid climates benefit most from the combination of agriculture and PV farms. Image: Iberdrola. Combining solar modules and crops in an area is not a new idea in the PV industry since it could ...

NORFOLK, Va. — After Monday’s winter weather, areas around the Peninsulas and the western Southside accumulated three or more inches of snow. And that snow slightly affected high temperatures this ...

A high reflectivity mirror, also known as a supermirror, is a dielectric mirror that has been carefully designed to provide optimal reflectivity while minimizing any scatter and absorption effects.

Researchers have conducted a detailed study of the albedo (reflectivity) effects of converting land to grow biofuel crops. Based on changes in albedo alone, their findings reveal that greenhouse gas ...
