On Wednesday, March 23, Steven Pawson, an atmospheric scientist and the chief of the Global Modeling and Assimilation Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will present a lecture called “El Niño: A NASA Perspective” in the Pickford Theater on the third floor of the Library’s Madison building, from 11:30 a.m. to 12:30 p.m. His presentation will cover the broad characteristics of El Niño, followed by a detailed view of the 2015-2016 event and description of how scientists use computer models to build up a three-dimensional picture of El Niño in the oceans and atmosphere, as well as how NASA uses space-based observations to form a more complete picture of the impact of El Niño on the global earth system.
