1. Contents of these proceedings. These proceedings contain most of the
papers which were presented at the NATO ARW (Advanced Research Workshop)
on "Large Scale Computations in Air Pollution Modelling". The workshop
was held, from June 6 to June to, 1998, in Residence Bistritza, a
beautiful site near Sofia, the capital of Bulgaria, and at the foot of
the mountain Vitosha. 2. Participants in the NATO ARW. Scientists from
23 countries in Europe, North America and Asia attended the meeting and
participated actively in the discussions. The total number of
participants was 57. The main topic of the discussions was the role of
the large mathematical models in resolving difficult problems connected
with the protection of our environment. 3. Major topics discussed at the
workshop. The protection of our environment is one of the most important
problems facing modern society. The importance of this problem has
steadily increased during the last two-three decades, and environment
protection will become even more important in the next century. Reliable
and robust control strategies for keeping the pollution caused by
harmful chemical compounds under certain safe levels have to be
developed and used in a routine way. Large mathematical models, in which
all important physical and chemical processes are adequately described,
can successfully be used to solve this task.
