Beschreibungen/Notizen

• The production rate of beryllium-7 is maximal in the stratosphere, decreasing approximately exponentially with decreasing altitude. Data are presented from an extensive monitoring program, conducted at the University of Milan, Italy, which has monitored the presence of super(7)Be as a natural tracer of air masses arriving from the upper layers of the atmosphere. The data show a relative mean value despite daily variations. Correlations are also shown between relative super(7)Be increases and natural ozone contributions.
