While the role of reactive halogen species (eg Cl, Br) in the destruction of the stratospheric
ozone layer is well known, their role in the troposphere was investigated only since their …

The cycling of inorganic bromine in the marine boundary layer (mbl) has received increased
attention in recent years. Bromide, a constituent of sea water, is injected into the atmosphere …

Bromoform (CHBr3) is the largest single source of atmospheric organic bromine and
therefore of importance as a source of reactive halogens to the troposphere and lower …

This chapter provides an update on scientific progress since the previous Scientific
Assessment of Ozone Depletion (WMO, 1999) regarding ozone-depleting substances …

In the Arctic winter 1998/99, two balloon payloads were launched in a co‐ordinated study of
stratospheric bromine. Vertical profiles (9–28 km) of all known major organic Br species …

Tropospheric BrO profiles (about 0.6±0.2 ppt, and 2.0±0.8 ppt at profile maximum) were
measured for the first time. Our measurements add new information to recent speculations …

The first tropospheric and stratospheric (4 to 33 km) BrO profile is presented for the inner
tropics derived from balloon-borne DOAS (Differential Optical Absorption Spectroscopy) …

We have measured bromoform (CHBr3) in the troposphere and lower stratosphere (sea
level to 17 km) from balloons, aircraft and ground stations. The concentrations ranged from 2 …

We report upper limits of lower stratospheric IO (inferred lowest values: 0.10 ppt, 0.07 ppt,
and 0.06 ppt at 20, 15, and 12.5 km, respectively) and OIO (inferred lowest values: 0.10 ppt …

The total stratospheric inorganic bromine burden (Bry) was derived from balloon‐borne
bromine monoxide (BrO) observations performed with the LPMA/DOAS (Limb Profile Monitor …
