In Memoriam – David John Hall

It is with great sadness that we learnt of the death of Dr David Hall on 22nd February 2015. David has been a leading figure internationally in plume dispersal measurement and modelling, and in atmospheric sampling of dusts and aerosols. Formerly at Warren Spring Laboratory and the Building Research Establishment, since setting up “Envirobods” in 1999 David and his colleague Angela Spanton continued with plume dispersal research and studies into the dispersal of contaminants during major incidents. Among the many projects David was engaged in towards the end of this life was Chapter 6 “Dispersion of Fire Plumes in the Atmosphere”, which provides a fitting memorial to his practical expertise and enthusiasm for this important subject.
