Earth & Atmospheric Science: Atmospheric Science Stream

Atmospheric Science

In Canada, weather plays a key role in our daily social and economic activities, and is a major concern in travel and aviation safety.  Over the last few decades. human activities have had a major impact on the ozone layer, sea levels, glacial ice sheets and the Earth’s climate itself, rendering weather prediction one of the most important applications in Atmospheric Science.

The EATS program is devoted to increasing our understanding of the composition, chemistry and dynamics of the Earth, and its atmosphere, ionosphere and magnetosphere, and to the exploration and study of similar processes on other planets. Climate change on regional as well as global scales are major areas of applications.

Atmospheric Science explores meteorology from the turbulent micro scale to the large synoptic scale weather systems. In our program, you will learn how we use computer models to forecast the weather and will develop a deeper understanding of the processes that drive severe weather, climate and climate change. You can top off your degree with a Certificate in Meteorology.

Undergraduate Degree: BSc. Atmospheric Science

Certificate: Meteorology

Courses You’ll Take:

  • Geophysics and Space Science
  • Cloud Physics and Radar Meteorology
  • Numerical Weather Prediction
  • Climate and Climate Change
  • Remote Sensing of the Atmosphere
Degree Checklists

Degree Checklists are a complete listing of all program-specific courses required for successful graduation. The degree checklists for the BSc. EATS and Specialized Honours Atmospheric Science program for the last four years are listed below:

Degree Breakdown
  • Foundational Courses in Chemistry, programming, applied calculus, linear algebra and physics
  • applied courses in programming
  • applied courses in statistics, calculus and numerical prediction
  • applied courses in physics, atmospheric chemistry
  • applied courses in meteorology, spatial analysis, geography
  • a final year research course
  • choice of electives in specialized program courses such as remote sensing, climate science, storms and weather systems

York graduates from both our Atmospheric Science stream and our one-year Certificate of Meteorology have been employed by:

  • Environment and Climate Change Canada’s Meteorological Service
  • The Weather Network
  • Ontario Ministry of the Environment and Climate Change
  • government agencies for Natural Resources
  • risk management in the insurance industry
  • private environmental consulting

Note the Department’s Certificate of Meteorology satisfies Environment and Climate Change Canada’s entrance requirements for training as a government meteorologist.

Why Atmospheric Science?

Weather prediction, modelling and climate science: these are the big contributions made by the work of Atmospheric Scientists throughout their careers. Atmospheric Scientists study, learn and master the science behind the functioning of our natural world, and devise models to help us anticipate them. Thanks to the work of these scientists, we can gather increasingly accurate data about weather systems, effects on the natural environment , and effects on everyday human activity.

In a world that is steadily seeing the effects of global warming and climate change, Atmospheric Scientists are key in understanding the severity of our situation, and predicting the factors which can help mitigate them.

Notable alumni and faculty: Dr. Tom McElroy, who devised the UV Index employed in weather prediction today, Dr. Peter Taylor, whose work on the impact of Lake Erie Wind Farms on Water Temperature and Mixed-Layer Depths was published on the front cover of the March issue of the Journal of Geophysical Research.
