2018 Summer Course

Course on Applications of LibRadtran for Studying Interactions of Radiation with Aerosols and Clouds

Universidade de São Paulo & Norwegian Institute for Air Research

5 - 14 November 2018

Scope:

Radiation transfer in the atmosphere is fundamental to understand atmospheric physics processes. It is the energy source for winds and convection, biosphere- atmosphere interactions and is at the heart of climate stability as well as climate change. Aerosol physics is also strongly connected to radiation by photochemistry processes. Clouds interact with radiation both in shortwave and longwave spectra in such a complex way that is not fully understood. The modeling of all these interactions is crucial to advance the understanding of physical processes in the atmosphere, and LibRadtran is a state-of-the-art tool to numerically model these effects in a myriad of situations. This course will give students training on such numerical simulations at a level required for scientific research.

The course main Lecturer is Professor Arve Kylling, from the Norwegin Institute for Air Research, and one of the main developers of Libradtran. The course aims to promote the interaction between Dr. Kylling and students interested in radiative transfer in the atmosphere that already use, or plan to use, LibRadtran as a modeling tool. It is expected that students will strongly interact with Dr. Kylling and learn how to use the model to tackle important scientific questions, such as scattering by non-spherical particle and tridimensional effects. For that, the course will include theory, practice and personal tutoring sessions.

The course includes:

  1. Modeling absorption and scattering of solar radiation in the atmosphere;
  2. Modeling thermal infrared radiation transfer in the atmosphere;
  3. Modeling light scattering by atmospheric particulates;
  4. Modeling radiation transfer in 3D;

Requirements:

  • Lectures will be conducted in English. Applicants therefore must be proficient or have a sound understanding of the English language in order to understand, communicate, and participate actively in the school activities.
  • Background on electromagnetism and/or radiative transfer in the atmosphere is needed. Prior contact with LibRadtran is advantageous, but not required.
  • Each participant should have a laptop with linux, with C and Fortran compilers. For those who do not have that, access to a local computer will be provided on site.
  • Data analysis software to process LibRadtran output is free of choice, but should be able to read in ASCII files (Matlab, R, Gnuplot, Python, Excel, etc.).
