Diamond dust is a ground-level cloud composed of tiny ice crystals. This meteorological phenomenon is also referred to simply as ice crystals and is reported in the METAR code as IC. Diamond dust generally forms under otherwise clear or nearly clear skies, so it is sometimes referred to as clear-sky precipitation.

Dec 18, 2024 · New research indicates that shooting 5.5 million tons (5 million metric tons) of diamond dust into the stratosphere every year could cool the planet by 1.8 degrees Fahrenheit (1 degree Celsius)...

Jan 31, 2024 · Can it really snow from a cloudless sky? Learn about the meteorological phenomenon known as diamond dust and how and where it forms.

Jul 2, 2024 · Diamond dust is a form of precipitation consisting of slowly falling, minute, unbranched ice crystals that often appear to float suspended in the air. They float through the air very slowly...

Aug 1, 2017 · What Is Diamond Dust? Diamond dust is most common in frigid temperatures. Low level clouds that exist in the form of tiny crystals are called diamond dust. The diamond dust is usually first noticed when the tiny crystals reflect sunlight …

Jan 9, 2011 · Diamond dust is a cloud composed of tiny ice crystals that forms near the ground. It is often reported under clear sky conditions and so is also known as ‘clear-sky precipitation.’ The formation of diamond dust requires very cold temperatures, typically less than minus-13.

Definition: Diamond dust: Precipitation that falls from a clear sky in very small ice crystals, often so tiny that they appear to be suspended in the air. Diamond dust can be observed in polar and alpine regions and continental interiors, especially in clear, calm and cold weather.

Apr 1, 2024 · Diamond dust is a type of atmospheric phenomenon that consists of tiny ice crystals suspended in the air. These ice crystals are so small and light that they can remain aloft for long periods of time, creating a shimmering effect that resembles diamonds glittering in the sky.

Aug 1, 2023 · Diamond dust forms close to the ground at very low temperatures during clear skies. These crystals are tiny (think on the scale of thousandths of an inch) and vary in shape from tiny hexagons to thin, long columns or short, stubby columns.

Oct 18, 2024 · A multi-institutional team of climatologists, meteorologists and Earth scientists has found evidence that dropping diamond dust from an airplane into the atmosphere could cool the planet.
