Perspectives on Operational Volcanic Ash Warnings

This paper discusses the Meteorological Service of New Zealand in Wellington, New Zealand. The Service provides a Volcanic Ash Advisory Centre (VAAC) and a Meteorological Watch Office (MWO). It also provides Volcanic Ash Advisory (VAA) messages and Significant Meteorological (SIGMET) information bulletins. Its VAAC operations cover much of the Southwest Pacific Ocean. The paper describes the structure of volcanic ash warning systems, the international aspects of warning services, what doesn't work and what does, and the development of customized services.
