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.

This course will give students training on such numerical simulations at a level required for actual 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.

Scope:

The scope of the course is on atmospheric aerosols and clouds with special focus on tropics and Amazonia. Participants on the course will use aerosol analysis and modeling tools based on the CALM aerosol process based model (Tuved et al, Atmos. Chem. Phys., 10, 10161–10185, 2010). The tools will be applied on real observational data from wider Amazon Basin. The main goal is to focus on understanding the major physical, chemical and optical processes, together with transport in the atmosphere, controlling aerosol properties and distribution in the atmosphere.

The course includes:

1. Lectures given by lecturers from University of Sao Paulo, Stockholm University and Lund University.
2. Introduction to aerosol dynamics and chemistry process based models
3. Introduction to cloud model
4. Practical part involving data analysis of the observations from Amazonia and use of the aerosol process based modeling tools

Themes for Modelling Exercises

Students will be divided into 3 - 4 groups depending on how many are present. The exercises will involve basic data processing and then testing several hypothesis/processes using set of modeling routines that can be combined together as building blocks.

Proposed themes for exercises are based on use of real data obtained during GoAmazon2014/15, but students are encouraged to bring their own datasets (see themes below). Specific scientific questions will be posed and evaluated using the modeling tools, guiding the students in their work. The five themes that will be developed are:

1. Evolution of aerosol size distribution of Manaus plume and assessing the importance or coagulation, condensation, dispersion and removal processes. For this part data from T2 and T3 sites provide the basis.
2. Why is the aerosol size distribution in remote areas so stable? Here we thought of students to use data from T0 (ATTO) and test different processes forming aerosol size distribution over the rainforest (coagulation, condensation, removal, changing emission gas phase precursors).
3. How do aerosols change clouds? here we propose to use data from T0 (clean) and T2 or T3 (polluted) and let students explore how different conditions and aerosol loading change the aerosol activation and resulting cloud microphysical properties. Besides different aerosol they can also test what more/less water vapor will do, etc.
4. Why we do not see new particle formation over rainforest? The nucleation routines from Peter's model will be used together with real conditions (T0 site for example) to test by varying thermodynamic conditions (p, T, RH, solar insulation) and available gaseous precursors if a treshold, where model allows occurence of nucleation as we know it from other parts of the world.
5. What is the direct radiative forcing of clean and polluted aerosol over Amazonas? Using aerosol optical data from T0, ZF2, T2 and T3 use the aerosol optical properties model routines to assess the direct radiative
