Alan Griffiths

Profile

 

Role at ANSTO 

 

Alan studies atmospheric mixing and transport in the lower atmosphere within the Isotopes in Climate Change & Atmospheric Systems program. Activities include field data acquisition and analysis, including eddy covariance flux measurements; lidar remote sensing of the boundary layer; and modelling studies using meteorological and dispersion models. Recent work includes testing parameterisations in an atmospheric model using airborne radon measurements and mapping radon exhalation at the Australian land surface.

 

Expertise


Micrometeorology, boundary-layer meteorology, atmospheric turbulence, modelling, radioactive tracers, model verification, lidar remote sensing.
