Objective
To study the tropospheric abundance, reaction cycles, loss processes, and effect of Reactive Halogen Species in the troposphere, in particular with respect to their influence on the total oxidation capacity of the troposphere (marine and
This study is a contribution to the part of the programme dealing with the Oxidation Capacity of the
Troposphere. It will be achieved by coordinated field-, laboratory- and modelling investigations of reactive
halogen species, their precursor and storage species, and the reaction mechanisms involved. Field measurements
will include direct determination of halogen oxides by Differential Optical Absorption Spectroscopy (DOAS)
at sub-ppt levels. The laboratory studies will close many gaps in our knowledge of RHS related homogeneous
and surface-catalysed reactions including iodine chemistry. The latest data from field and laboratory studies will
be assembled in trajectory- and limited area 3D models, which will help to understand the results of the field
campaigns as well as to assess the regional and global impact of RHS chemistry. A further important part of
this study will be the assessment of a possibly anthropogenic influence on RHS sources and the transformation
mechanisms within the RHS reservoir. Thus possible mechanisms changing the tropospheric oxidation capacity
due to human activities can be investigated. While a central question concerns the importance of release of RHS
from sea salt aerosol, for instance due to reaction of anthropogenic NOy species (like N205, NO2) with sea salt
aerosol, the detailed investigation of those processes is the aim of a parallel study with the sub-title "Sea Salt
Aerosols: Laboratory Investigation of Heterogeneous Halogen Activation in the Troposphere
(HALOTROP-SALT)". Areas where enhanced levels of RHS are to be expected (like polluted coastlines or
polar regions) will be identified. Regional processes involving RHS will be set into a global perspective.
