NOAA scientists investigating the stratosphere have found that in addition to meteoric ‘space dust,’ the atmosphere more than seven miles above the surface is peppered with particles containing a variety of metals from satellites and spent rocket boosters vaporized by the intense heat of re-entry.
The discovery is one of the initial findings from analysis of data collected by a high-altitude research plane over the Arctic during a NOAA Chemical Science Laboratory mission called SABRE, short for Stratospheric Aerosol processes, Budget and Radiative Effects. It’s the agency’s most ambitious and intensive effort to date to investigate aerosol particles in the stratosphere, a layer of the atmosphere that moderates Earth’s climate and is home to the protective ozone layer.
