❝ On August 8, 2019, a team of atmospheric scientists got an exceedingly rare look at fire clouds as they were forming. NASA’s DC-8 flying laboratory passed directly through a large pyrocumulonimbus that day as it was rising from a fire in eastern Washington. The flight was part of a joint NOAA and NASA field campaign called FIREX-AQ. Scientists are studying the composition and chemistry of smoke to better understand its impact on air quality and climate…

❝ The photograph above, shot from roughly 30,000 feet (9 kilometers), shows the setting Sun shining through thick smoke at 8 p.m. Mountain Time. Particles in the smoke reflect light in ways that make the Sun appear orange…

The flight was the most detailed sampling of a pyrocumulonimbus in history, explained Peterson. A second research aircraft flew over the plume a few hours earlier in the day, and mobile labs on the ground also made detailed measurements.

Amazing photos. Quality and timing should offer useful analysis, learning for future events and their global effect.
