Course purpose

This course will focus on measuring environmental data related to various environmental processes (e.g., meteorological transport, atmospheric chemistry) and atmospheric states over time and space (e.g., concentrations of gases and particles, radiation).

The course will emphasize measurement uncertainties, error propagation, and data representativity—key concepts when using data as inputs in modeling.

Practical projects and laboratory exercises involving real atmospheric and environmental measurements will be integral to the course, allowing students to develop hands-on skills. The course also includes an exam covering all course elements, with additional readings required to achieve higher grades.

Attendance and final exam

Experiments, study visit and guest lectures are compulsory.

The final exam will include questions about lectures, guest lectures, experiments and study visit.

Course design

This is an experimental course with less emphasis on the techniques, and more on the planning, execution, reporting, and use of experimental work.

The course starts with a series of general lectures on environmental problems, the principles of spectroscopy, uncertainty analysis, remote and in-situ measurement techniques. This is used as the foundation for the design and practice of experiments. Knowledge is completed through quizzes and active learning in the classroom.

Experiments are designed to promote the creativity and initiative of the students. The goal is to gain insight on the complexity of all stages of an experiment and how to make use of the results for modelling purposes. Three experiments will be done using in-situ methods and remote sensing of gases, particles, and biological material under natural conditions.

Reports are an important part of the course, they should be formulated clearly, completely, and accurately. They should allow another experimenter to reproduce the results.

Guest lectures and study visits will be offered to expand the views and share expertise related but not identical to what is learned through the experiments.

Supervision will be offered to plan, conduct, and analyze the results of experiments.

A seminar with presentations of results will be organized to compare and discuss the different findings.

The final exam will include questions from all lectures, experiments, and the study visit.

Learning objectives and syllabus

Learning objectives:

  • Give examples of important environmental problems and explain the physical and chemical processes involved.
  • List different measurement techniques that are commonly used to address these environmental problems and perform the corresponding measurements.
  • Explain how geophysical information can be extracted from remote sensing and invasive/extractive measurements.
  • Describe data evaluation, from measurement to geophysical product.
  • Demonstrate an understanding of how uncertainties in measured data can affect model outputs.

Safety considerations

  • The experiments of this course will not include the exposure to dangerous substances, nor the handling of dangerous equipment.
  • All equipment should be used with the consent and following instructions of a supervisor.
  • There is also room for creativity in the design of the experiments, but any potential risk must be discussed and approved by the teachers.
