Description
σ-FORUM is a powerful and multipurpose radiative transfer code, developed for studying Earth's atmosphere in the longwave radiation. It manages to produce high-resolution spectra while remaining a fast code by using parametrized optical depths. It allows the computation of fast analytical derivatives of the radiance with respect to atmospheric properties, thus being suitable for the application in fast retrieval of IR instruments.
In the context of the “Earth-Moon-Mars” project by INAF, ASI, and CNR, this work aims to expand our knowledge of the Martian atmosphere and, in a comparative planetology approach, also Earth's, extending the application of the σ-FORUM code to the atmosphere of Mars. Exploiting its flexibility and capabilities, in particular speed and accuracy, σ-FORUM will be a powerful tool for the simulation of the Martian spectrum and retrieval of its atmospheric quantities.
The work, that will converge in a PhD thesis is at its first stages, where the optical depths for the Martian atmosphere are being computed by means of the Planetary Spectrum Generator (PSG), a line-by-line powerful radiative transfer model suite for simulating planetary spectra for a broad range of wavelengths, different geometry and observatories.
