CREATE-AAS Science In Brief: Measurements of Transported Wildfire Pollution in Eureka
Author: Tyler Wizenberg, PhD Candidate, University of Toronto The high Arctic is often viewed as a pristine, untouched wilderness, far away from human influence. However, in reality this is not always the case and large-scale atmospheric circulation patterns can enable … Continue reading

CREATE-AAS Science In Brief: On Improving Measurements of Atmospheric Water Vapour
Author: Dr. Ellen Eckert, Postdoctoral Fellow, University of Toronto When atmospheric scientists aim to improve measurements of an atmospheric quantity like water vapour, they commonly start off by examining the quality of new observations. This step is called validation. For … Continue reading

Temperature inversion in the Arctic
Under normal conditions, the temperature in the lowest layer of the atmosphere (the troposphere) decreases with height. The higher you go, the colder the temperature becomes. This is why there can be snow-capped mountains in warm climates. However, something quite … Continue reading
