WACCM response to solar cycle featured in EOS spotlight

A research paper co-authored by ACOM scientist Dan Marsh was featured in Eos. The paper describes how WACCM version 4 produces a stronger vertical circulation in the earth's atmosphere, bringing NO and NO₂ down into the stratosphere over Antarctica and destroying ozone there. WACCM4 provides the basis for new studies that may increase our understanding of the sun’s impact on climate. The original paper "Simulated solar cycle effects on the middle atmosphere: WACCM3 Versus WACCM4" was published in Journal of Advances in Modeling Earth System (June 2015).
