Dust Formation, Injection, and Continental Aridity

Those scientists studying the mechanisms of dust production and injection and their relationship to aridity found a need for two scales of studies of these processes — fine-scale point source studies and broad-scale studies applicable to receptor-type models. Fine-scale point source studies, which are presently being made by geomorphologists, are necessary to understand the type of material which is being generated and injected into the air and the details of the climatic conditions which control that generation and injection. The second scale of studies necessary in the future are broad-scale, receptor-type models which can be translated into formulations for use in global circulation models. Although the group felt that the overall direction of present studies of dust formation and injection is appropriate, they felt that expansion of their studies and a few changes of emphasis would be useful to link their work to that of other scientists studying dust transport and deposition. They also emphasized that some of this work should be co-operative with other groups.
