Report on an informal conference in atmospheric chemistry held at the Meteorological Institute, University of Stockholm, May 24—26, 1954

In October 1952 a small conference was held at the Institute of Meteorology of the University of Stockholm to discuss research problems in cloud physics. At that time a first attempt was made to focus the attention of meteorologists on the important role played by the general atmospheric circulation in the transport and redistribution of certain chemical elements which are of interest to cloud physicists but also, though for somewhat different reasons, to such diverse groups as students of agronomy, of atmospheric pollution and of general geochemistry.
