Dr. J.L. Brenguier, Meteo-France,
Coordinator of the ACE-2
CLOUDYCOLUMN and PACE project
CLOUDYCOLUMN, one of the five projects in the
second aerosol characterization experiment took place in June-July 1997 in the
Canary Islands. Designed as a closure study, the field campaign involved in
situ measurements of the aerosol physical and chemical properties, cloud
microphysics and cloud radiative properties. Following the analysis of the
CLOUDYCOLUMN experiment, the PACE project (Parameterization of the Aerosol
Climatic Effect) brings together experimentalists from Météo-France, the
University of Wyoming DAS, the Universities of Berlin and Warsaw, and climate
modellers.
Results of the closure study will be presented as well as the design of the initialisation data set for the simulation of the selected case studies. Numerical experiments will be discussed to show the obstacles and preliminary results in the simulation of the aerosol indirect effect.
