Interactions between radiation and atmospheric particles are central to Earth’s radiation balance and climate system. Scattering and absorption by aerosols and cloud particles govern atmospheric heating rates, yet accurately quantifying the radiative effects of aspherical particles remains a major challenge for both measurements and models. While numerically exact methods exist for small particles, uncertainties in morphology and the computational cost of modeling large and complex particles necessitate simplified approaches.

This session provides a forum for the measurement and modelling communities to exchange new insights and approaches.
