Flying through a fire cloud ☁️🔥☁️
This photo from roughly 30,000 ft (9 km) shows how smoke particles reflect light in ways that make the Sun appear blazing orange. Our DC-8 flying laboratory passed directly through a large fire cloud — called a pyrocumulonimbus — on August 8 as it was rising from a fire in eastern Washington, giving scientists a look at the phenomena. These clouds form when the intense heat of wildfires lift the smoke above the boundary layer, the lowest part of Earth's atmosphere.
The flight was part of a joint NOAA and NASA field campaign called FIREX-AQ. Scientists are studying the composition and chemistry of smoke in the atmosphere to better understand its impact on air quality and climate.
