About IPRT

The International working group on Polarized Radiative Transfer (IPRT) has been initiated in June 2011. Its objectives include:

  • compare and improve polarized radiative transfer models
  • provide benchmark results
  • develop publically available codes
  • provide information about free codes
  • provide input data (scattering matrices, BPDFs)
  • bring community together (workshops, …)


A model intercomparison study for vector radiative transfer simulations in spherical geometry has been performed and is published along with the benchmark results:

D. Zawada, G. Franssens, R. Loughman, A. Mikkonen, A. Rozanov, C. Emde, A. Bourassa, S. Dueck, H. Lindqvist, D. Ramon, V. Rozanov, E. Dekemper, E. Kyrölä, J. P. Burrows, D. Fussen, and D. Degenstein. Systematic comparison of vectorial spherical radiative transfer models in limb scattering geometry. Atmos. Meas. Tech., 14(5):3953-3972, 2021.

Benchmark results for coupled atmosphere-ocean systems have been produced by a Science Team for the upcoming Earth-observing NASA/PACE mission:

Jacek Chowdhary, Peng-Wang Zhai, Feng Xu, Robert Frouin, Didier Ramon, Testbed results for scalar and vector radiative transfer computations of light in atmosphere-ocean systems, JQSRT, Volume 242, 2020

Phase B (3D test cases) of the model intercomparison has been published: Emde et al. 2018, JQSRT. The benchmark results can be downloaded here.
