Processes Operating at the Surface and in the Subsurface of the Atacama Desert

Extreme precipitation events that impacted northern Chile in the last several years raise the question, ‘Are these rains driven by modern climate change and an omen of the future, or are these simply examples of the rains that have intermittently shaped the Atacama Desert landscape over the last several millennia, yet have been rarely witnessed?’. Through a combination of novel remote sensing methods and field observations, I work with colleagues and students to quantify the impacts of those events across the landscape.
