| Summary | We will explore the chemical composition of the atmosphere, with an emphasis on the troposphere (lowest 10-15 km of the atmosphere) where we live and breathe. We will study the surface processes and atmospheric chemistry and transport that determine observed variations in regional and global tropospheric chemical composition. We will cover the fundamentals of atmospheric chemistry (e.g., kinetics, photolysis) so there is no chemistry pre-requisite to this course. The course content, as described below, will be delivered using online material, online class interaction, problem sets and additional reading. |

Written Exam: 50%, Course Work: 50%
The formal written exam will take the form of two numerical questions.
The course work includes two computer labs, each including a directed 300-word literature survey. Both directed literature surveys will include pre-assigned papers to review and summarise.
The literature surveys will be marked following the common marking scheme.

Assessment Deadlines
Assessed computer labs, including directed literature surveys, will be set in Weeks 5 and 8 of semester 2 and due on the Wednesday of Weeks 6 and 9 of semester 2, respectively, at 12 noon via online submission. The formal written exam will be sat in the May exam diet.
Assessed Computer Lab 1: Semester 2, Wednesday Week 6, 12noon (online via Turnitin)

| Feedback |
Lecturer-student feedback will be provided on the:
responses to the two assessed computer labs in Weeks 5 and 8
two 300-word literature surveys that accompany the two assessed computer labs, outlining the strengths and weaknesses of the composition and analysis as per the assessment instructions
exam script in written form
There will be an opportunity to get feedback during class as part of interactive discussions.
Tutor-student feedback will be provided via targeted revision classes throughout the semester. These sessions will support the learning outcomes of the class activities.
