This course is focused on fundamental understanding of radiation processes such as absorption and scattering on the molecules,

aerosols, and clouds as well as the radiative transfer in atmosphere.

Program:

1. Definitions of key quantities and principle of black body radiation

2. Absorption of radiation in the atmosphere

- absorption spectrum of atmospheric gasses

- HITRAN database

- simulation of absorption properties

3. Scattering of radiation in the atmosphere

- Rayleigh scattering

- Lorenz-Mie scattering

- geometric scattering.

- discrete dipole approximation

- simulation of single scattering properties

3. Introduction to radiative transfer equation

- Lambert-Beer low

- general form of the radiative transfer equation

- boundary condition at the top of the atmosphere and at the Earth's surface.

4. Approximate and accurate numerical solutions of radiative transfer equation.

- single scattering approximation

- two streams approximation

- delta-Eddington method

- Monte Carlo methods,

- discrete ordinate method.

5. Radiative transfer models

- MODTRAN,

- Fu-Liou

6. Simulation of short- and longwave fluxed by radiative transfer models

- definition of different atmospheric conditions and simulation scenario

- estimation of radiative forcing
