SODA Workshop on Chemical Data Assimilation Proceedings 9-10 December 1998

The workshop reviewed several aspects of chemical data assimilation, and the program was divided in five sessions: the observation system for atmospheric composition measure­ments, atmospheric chemistry and its parameterisation, the ozone structure generated by the atmosphere's dynamics, ozone data assimilation, and advanced chemica! data assim­ilation systems. The summary and outlook below are following these themes.
