Aerosol model ECHAM-HAM

Aerosols are very small particles floating in the air. They play a significant role within the global climate system. By absorption and scattering they influence the global radiation budget directly as well as indirectly by modification of cloud properties.

The development, interaction, and spreading of aerosols of different sources can be simulated with the new aerosol-climate model ECHAM5-HAM. (Data: Philip Stier, University of Oxford, formerly MPI f. Meteorology)

This animation shows the simulated development of five different aerosols over the course of the year. The model includes natural aerosols like sea salt and dust as well as substances more related to human activities.

A slightly different version of the animation is also available for download (MPEG1, 10 MB):


More information on the model can be found in the publications on the web pages of the Department of Physics, University of Oxford.
