Researchers Measure Overlooked Stratospheric Aerosols
In 2023, NASA’s WB‑57 high‑altitude aircraft, equipped with a custom instrument, measured aerosol particles smaller than 150 nm in the lower stratosphere for the first time. The data revealed that these ultra‑fine, organic‑rich particles dominate the surface area available for stratospheric chemistry, a component previously invisible to satellite and balloon sensors. The findings, published in Science, suggest that current atmospheric models underestimate the chemical complexity and radiative impact of the stratosphere. The work was part of NOAA’s SABRE campaign aimed at refining Earth’s radiation budget.
