UK SOLAS Reactive halogens in the marine boundary layer (RHaMBLe) campaign at Roscoff, Brittany, France (July-August 2006)

The UK SOLAS Reactive halogens in the marine boundary layer (RHaMBLe) campaign aimed at quantifying marine halogen cycling and investigating its spatial variability. The aim was also to determine the effects of marine halogen cycling on atmospheric oxidative chemistry. Coastal observations were made during the summer of 2006 at Roscoff Bay,Brittany, France. Measurements included trace molecules and radicals, aerosol characteristics and distribution. The coastal component of RHaMBle, carried out in Roscoff bay provided direct observational linkage between new particle formation and reactive halogens, resulting in the development of a new parameterisation for use in large-scale models.
