Caption: Up to 1,000 meters above the ground: as part of the EU project PEGASOS, Jülich scientists and their colleagues spent five weeks recording data with the Zeppelin NT in the atmosphere over northern Italy. During their campaign, the researchers identified a previously unknown process that leads to the formation of the trace gas nitrous acid (HONO). Data analysis led to a surprising finding: in contrast to the prevailing assumption, HONO is not an additional source of hydroxyl radicals (OH radicals), which play an important role in the atmosphere's self-cleaning capacity.
