Can statistics of turbulent tracer dispersion be inferred from camera observations of SO2 in the ultraviolet? A modelling study.
Kylling, Arve; Ardeshiri, Hamidreza; Cassiani, Massimo; Dinger, Anna Solvejg; Park, Soon-Young; Pisso, Ignacio; Schmidbauer, Josef Norbert; Stebel, Kerstin; Stohl, Andreas (Peer reviewed; Journal article, 2020)Atmospheric turbulence and in particular its effect on tracer dispersion may be measured by cameras sensitive to the absorption of ultraviolet (UV) sunlight by sulfur dioxide (SO2), a gas that can be considered a passive ... -
Observation of turbulent dispersion of artificially released SO2 puffs with UV cameras
Dinger, Anna Solvejg; Stebel, Kerstin; Cassiani, Massimo; Ardeshiri, Hamidreza; Bernardo, Cirilo; Kylling, Arve; Park, Soon-Young; Pisso, Ignacio; Schmidbauer, Norbert; Wasseng, Jan Henrik; Stohl, Andreas (Journal article; Peer reviewed, 2018)In atmospheric tracer experiments, a substance is released into the turbulent atmospheric flow to study the dispersion parameters of the atmosphere. That can be done by observing the substance's concentration distribution ... -
On the Convergence and Capability of the Large-Eddy Simulation of Concentration Fluctuations in Passive Plumes for a Neutral Boundary Layer at Infinite Reynolds Number
Ardeshiri, Hamidreza; Cassiani, Massimo; Park, Soon-Young; Stohl, Andreas; Pisso, Ignacio; Dinger, Anna Solvejg (Peer reviewed; Journal article, 2020)Large-eddy simulation (LES) experiments have been performed using the Parallelized LES Model (PALM). A methodology for validating and understanding LES results for plume dispersion and concentration fluctuations in an ...
