Admission  SCIENCE (JS4601)  OR
Earth System Science (Atmospheric Science / Geophysics) (JS4633)


Earth System Science (ESSC) studies the dynamics of the Earth as an interrelated system that includes the atmosphere, biosphere, geosphere, and hydrosphere, as well as human impacts. ESSC offers two streams, for students who want to pursue in-depth studies in either “Atmospheric Science” or “Geophysics”. Both streams provide students with training in the basics of these sub-disciplines and introduce useful quantitative tools.


The ESSC programme provides students with solid scientific and mathematical foundation of the Earth System. The focus is on physical processes within different ‘spheres’, the interactions between them and how they shape the Earth's environment. Students who take this programme will be equipped with strong analytic and computational skills. They can build their research and career capacities via laboratory work, numerical modeling and programming, seminars, workshops and research projects.

Career Prospects

Students can pursue further studies in Earth System or related sciences, or they can embark on careers in education, weather and climate services in the government or private sector, NGOs, environmental consultancy, exploration of natural resources including petroleum and natural gas, geotechnical engineering, information technology, data analytics and other sectors requiring strong quantitative or analytic skills.

CHAN Yuk Chun 

Choosing Earth System Science as my undergraduate major has been one of the best decisions I have ever made. The well-designed curriculum helped me to acquire all the essential knowledge and techniques for studying the complicated natural phenomena on the
earth. The training for conducting quantitative analysis is also valuable for finding competitive jobs in the current data-driven world. Meanwhile, the programme provided the flexibility for me to incorporate other learning experiences into my undergraduate education. Through participating in an internship at the Hong Kong Observatory, summer laboratory placements and an overseas exchange programme, I have explored different research areas in the domain and figured out my interest in investigating problems in atmospheric modelling. More importantly, I found my lifelong calling to combat climate change and environmental degradation after all the adventures.
