Type of module:

Summary module description:

Molecular spectroscopy as applied to molecules of atmospheric relevance.

Aims:

This module aims to provide students with an understanding of molecular spectroscopy, from an environmental physics perspective, to enable a deeper understanding of radiative transfer in the Earth’s atmosphere, with particular relevance to climate change and remote sensing.

Assessable learning outcomes:

By the end of the of module students will:

• Understand the main fundamental physical mechanisms that describe how molecules absorb and emit radiation, and how this is determined by the underlying molecular structure;


• Have an overview of the main experimental techniques used to probe the spectroscopic properties of molecules, including an understanding of the limitations of these techniques;


• Develop a quantitative understanding of the spectroscopic properties of important atmospheric gases and how these are represented on molecular databases.

Additional outcomes:

Outline content:

• Fundamentals of molecular spectroscopy – quantum mechanical and semi-classical description of electronic, vibrational and rotational transitions. Dependence of spectra on molecular structure, and the role of degeneracy and Fermi resonance in determining the spectra;


• Introduction to the main experimental techniques for measuring spectroscopic properties of molecules;


• Molecular databases, especially HITRAN, and their use in line-by-line radiative transfer codes;


• Application of understanding to selected atmospheric molecules, including water vapour, carbon dioxide, methane, oxygen and heavier halogenated molecules.

Brief description of teaching and learning methods:

Students are expected to independently access the learning materials, including online lecture notes and pre-recorded videos provided by the lecturer, and use the tutorials (9 hours) and the computing practical class (2 hours) to improve their understanding of the topics covered.

Summative assessment- Examinations:

2 hours.

The examination for this module will require a narrowly defined time window and is likely to be held in a dedicated exam venue.

Summative assessment- Coursework and in-class tests:
Two assignments, including one based on the computing class.

Formative assessment methods:

Problem sheets handed out in class.

Penalties for late submission:

The Support Centres will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
• where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

The University policy statement on penalties for late submission can be found at: /cqsd/-/media/project/functions/cqsd/documents/cqsd-old-site-documents/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Assessment requirements for a pass:
A mark of 40% overall.

Reassessment arrangements:
Re-assessment by examination in August/September
