Welcome to the Department of Atmospheric and Oceanic Science. The Department, part of the Earth Sciences Program that includes the collocated Earth System Science Interdisciplinary Center, offers undergraduate and graduate degrees in atmospheric and oceanic sciences, and climate earth sciences.
The department's research strengths are reinforced by strong collaborations leading to joint research topics with NASA Goddard Space Flight Center, Maryland Departments of the Environment and of Natural Resources, the National Centers for Environmental Prediction of the National Weather Service, the NOAA Satellite and Air Research Laboratories, all of which are located near the campus.

Congratulations to AOSC and ESSIC's Sumant Nigam and AOSC graduate student (and lead author) Natalie Thomas, co-authors of a new paper, “20th-Century Climate Change over Africa: Seasonal Hydroclimate Trends and Sahara Desert Expansion,” published online today in the Journal of Climate. The results of the study suggest that the Sahara Desert expanded by about 10 percent during the period spanning 1920-2013. The research is the first to assess century-scale changes to the boundaries of the world’s largest desert and suggests that other deserts could be expanding as well.
