Dr Alastair Williams

Research Leader, Atmospheric Research Group

Role at ANSTO

Alastair leads ANSTO-IER's Atmospheric Research Group. Group uses natural radioactive and stable isotopes as tracers to investigate the sources and movement of pollution and greenhouse gases in the lower atmosphere, and to aid in the interpretation of observed changes in atmospheric composition. Alastair conducts experimental boundary layer research using atmospheric Radon-222 to quantify vertical mixing processes in the lower atmosphere using aircraft and tower-based platforms. Alastair is also a member of the IER Management Team.


Boundary layer meteorology; micrometeorology; atmospheric turbulence; parameterisation of subgrid processes in numerical models; atmosphere-surface interactions; aircraft meteorological measurements; applications of radon in atmospheric studies.
