Shortwave and long-wave radiation, radiation transfer and global energy budget
This units introduces the concept of radiation transfer, the distinction of shortwave and long-wave radiation, spectral ranges, the interaction between matter and radiation. Furthermore, the global energy budget is discussed.
Learning goal
After successful completion of this unit you will be able to
- sketch the solar and terrestrial radiation
- describe the different behavior of shortwave and long-wave radiation, and their interaction with the atmosphere’s components
- solve simple problems related to shortwave and long-wave radiation processes
- interpret optical phenomena like halo, double rainbows, etc.
- name in which spectral ranges any given target has which characteristic interaction with radiation
- solve problems related to radiation – matter interaction (graduate students)
