Atmospheric residence time of CH sub(3)Br estimated from the junge spatial variability relation

The atmospheric residence time for methyl bromide (CH sub(3)Br) has been estimated as 0.8 plus or minus 0.1 years from its empirical spatial variability relative to C sub(2)H sub(6), C sub(2)Cl sub(4), CHCl sub(3), and CH sub(3)Cl. This evaluation of the atmospheric residence time, based on junge�...

Summary:The atmospheric residence time for methyl bromide (CH sub(3)Br) has been estimated as 0.8 plus or minus 0.1 years from its empirical spatial variability relative to C sub(2)H sub(6), C sub(2)Cl sub(4), CHCl sub(3), and CH sub(3)Cl. This evaluation of the atmospheric residence time, based on junge's 1963 general proposal, provides an estimate for CH sub(3)Br that is independent of source and sink estimates. Methyl bromide from combined natural and anthropogenic sources furnishes about half of the bormine that enters the stratosphere, where it plays an important role in ozone destruction. This residence time is consistent with the 0.7-year value recently calculated for CH sub(3)Br from the combined strength estimates for its known significant sinks.
