Measurements and modelling of molecular iodine emissions, transport and photodestruction in the coastal region around Roscoff
molecular iodine photodestruction the coastal region around Roscoff
2010/12/13
Iodine emissions from the dominant six macroalgal species in the coastal regions around Roscoff, France, have been modelled to support the Reactive Halogens in the Marine Boundary Layer Experiment (RH...

This paper presents a summary of the measurements made during the heavily-instrumented Reactive Halogens in the Marine Boundary Layer (RHaMBLe) coastal study in Roscoff on the North West coast of Fran...
Recent ground-based and space borne observations suggest the presence of significant amounts of iodine monoxide in the boundary layer of Antarctica, which are expected to have an impact on the ozone b...
The spatial distribution of the reactive iodine species IO from simultaneous active and passive DOAS observations
spatial distribution reactive iodine species IO DOAS observations
2010/3/1
We present investigations of the reactive iodine species (RIS) IO, OIO and I2 in a coastal region from a field campaign simultaneously employing active long path differential optical absorption spectr...
Simultaneous coastal measurements of ozone deposition fluxes and iodine-mediated particle emission fluxes with subsequent CCN formation

2010/1/18
Here we present the first observations of simultaneous ozone deposition fluxes and ultrafine particle emission fluxes over an extensive infra-littoral zone. Fluxes were measured by the eddy covariance...
Constraints on inorganic gaseous iodine in the tropical upper troposphere and stratosphere inferred from balloon-borne solar occultation observations
inorganic gaseous troposphere stratosphere balloon-borne solar
2009/10/9
We report upper limits of IO and OIO in the tropical upper troposphere and stratosphere inferred from solar occultation spectra recorded by the LPMA/DOAS (Limb Profile Monitor of the Atmosphere/Differ...
The time dependence of molecular iodine emission from Laminaria digitata

2009/3/13
We present the first in situ detection of molecular iodine emitted from the brown macroalga Laminaria digitata under natural stress conditions. We show that the release of I2 occurs in short, strong b...
Modelling transport and deposition of caesium and iodine from the Chernobyl accident using the DREAM model
Modelling transport deposition of caesium Chernobyl accident DREAM model
2009/3/12
A tracer model, DREAM (the Danish Rimpuff and Eulerian Accidental release Model), has been developed for modelling transport, dispersion and deposition (wet and dry) of radioactive material from accid...
Direct evidence for coastal iodine particles from Laminaria macroalgae – linkage to emissions of molecular iodine
