Unit Information

Earth's atmosphere comprises a thin layer of gravitationally bound gas and is all that separates us from the harsh environment of outer space. It is a complex system affected by many interacting physical, chemical, and biological processes. This unit investigates fundamental physical and chemical processes that determine atmospheric composition and structure, including techniques developed to measure them. It aims to provide a well rounded understanding of the key processes involved, gradually building up into a description of the complete atmosphere/climate system. It then moves on to consider the global climate system and climate change, including key ocean-atmosphere interactions and climate feedbacks. The techniques learnt will be used to explore the role of global feedback mechanisms and climate change. The course will also explore how these fundamental processes apply to other planets in our solar system.

Your learning on this unit

On successful completion of the unit you will be able to:

  • Account for the overall composition and structure of the atmosphere.
  • Understand the interaction of solar radiation with the Earth's atmosphere.
  • Use simple greenhouse models to determine surface and atmospheric temperatures.
  • Understand basic photochemistry and chemical lifetimes.
  • Be aware of key global chemical cycles including the carbon cycle and processes responsible for the ozone hole.
  • Describe observation techniques used to measure atmospheric properties.
  • Understand the processes involved in cloud formation.
  • Understand the effects of ocean circulation and polar ice caps on global climate.
  • Explain the effect of various feedbacks on the climate system.
  • Describe and interpret the evidence for climate change and use simple models to evaluate the effects of these changes.
  • Apply fundamental atmospheric science principles to other solar system bodies.

How you will learn

The unit will be taught through a combination of

  • asynchronous online materials and, if subsequently possible, synchronous face-to-face lectures
  • synchronous office hours
  • asynchronous directed individual formative activities and exercises
  • guided, structured reading
  • practical work in the laboratory

Students who either begin or continue their studies in an online mode may be required to complete practical work, or alternative activities in person, either during the academic year 2020/21 or subsequently, in order to meet the intended learning outcomes for the unit, prepare them for subsequent units or to satisfy accreditation requirements.

How you will be assessed

The unit will be assessed by an end-of-unit examination, which will cover concepts covered in the lectures and practicals.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EASC20027).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
