TL;DRAbstract

Our work as subproject P3 in the joint project EFEU aims for a better understanding of the interaction between biomass burning aerosol and radiation. The two main points are the single scattering properties and the multiple scattering between these particles, as described through the radiative transfer equation. The scattering and absorption properties of the single particles depend on the particle size, their morphology and composition. The regarded wavelength plays an important role, too. Information about the optical properties can be received either from experiments, like the ones that have been carried out by our EFEU project partners or by calculation with the help of our models. A comparison between the measured and modelled properties showed partially a good agreement. While we were able to demonstrate that the temporal development of the number size distribution is substantial, it has been shown that its temporal variation does not capture the resulting optical properties alon
