“NASA INSPYRE Campaign Hunts Wildfire-Spawned Pyrocumulonimbus Clouds” — what this page in the network covers. NASA scientists spent weeks this summer chasing a rare weather phenomenon: pyrocumulonimbus clouds, or pyroCbs, which are spawned by intense wildfires. The INSPYRE campaign—short for INjected Smoke and PYRocumulonimbus Experiment—focused on these fire-driven thunderclouds, which can inject smoke and pollutants high into the atmosphere. The effort gained urgency after the Wildhorse grass fire in eastern Idaho unexpectedly produced a massive pyroCb, sending a pulse of smoke skyward that no one had anticipated.
Researchers tracked such events to better understand how wildfire smoke affects weather, air quality, and climate. PyroCbs can reach the stratosphere, where smoke lingers for months, potentially altering atmospheric chemistry and even global temperatures. By studying these clouds in real time, NASA aims to improve forecasts of fire behavior and smoke dispersion, aiding emergency responders and public health officials.
