ATHAM (Active Tracer High Resolution Atmospheric Model)
The numerical model ATHAM (Active Tracer High Resolution Atmospheric Model) has been developed at the Max-Planck-Institute for Meteorology and the German Climate Computing Center in Hamburg. It is designed to simulate the mesoscale evolution of high energy plumes in the atmosphere focusing on processes near to the source. Its special ability is to deal with high gradients in temperature, pressure and velocity and with high particle concentrations. It has been applied to simulate typical plinian volcanic eruptions and biomass burning plumes.
