Climatology

Climatology is the study of the Earth's weather conditions over time. Colloquially speaking, climate is what you expect, weather is what you get. Climate is not constant, it changes in space and in time. The lessons in this unit will explore how scientists study past climates prior to satellite technology and expound upon how 21st century satellite systems help monitor global and regional climate conditions.
