A workshop was held in the framework of the ACCENT (Atmospheric Composition
Change – a European Network) Joint Research Programme on "Aerosols" and
the Programme on "Access to Laboratory Data". The aim of the workshop was
to hold "Gordon Conference" type discussion covering accommodation and
reactive uptake of water vapour and trace pollutant gases on condensed phase
atmospheric materials. The scope was to review and define the current state
of knowledge of accommodation coefficients for water vapour on water droplet
and ice surfaces, and uptake of trace gas species on a variety of different
surfaces characteristic of the atmospheric condensed phase particulate
matter and cloud droplets. Twenty-six scientists participated in this
meeting through presentations, discussions and the development of a
consensus review.
In this review we present an analysis of the state of knowledge on the
thermal and mass accommodation coefficient for water vapour on aqueous
droplets and ice and a survey of current state-of the-art of reactive uptake
of trace gases on a range of liquid and solid atmospheric droplets and
particles. The review recommends consistent definitions of the various
parameters that are needed for quantitative representation of the range of
gas/condensed surface kinetic processes important for the atmosphere and
identifies topics that require additional research. |
