Visiting Fellows Pellerin and Mallay present at Goddard Poster Symposium

The NASA Goddard Sciences and Exploration Directorate's Annual Summer Student Poster Symposium was held on Wednesday, August 5th in Goddard’s Hinners Auditorium. At this conference-style event, students, mentors, fellow researchers, and Goddard personnel celebrated the research accomplishments of the students over the summer. Among the ~110 presenters were GESTAR II Visiting Fellows Emma Pellerin (CSU) and Joshua Mallay (PSU). Additionally, several GESTAR II researchers served as mentors and attended with their summer interns.

Emma Pellerin and Viral Shah (610.1/Morgan) present "Probing Saharan dust and sea spray interactions with NASA Earth mission datasets: Implications for the global modeling of chlorine."  Joshua Mallay stands to the left of his poster in a pink polo.

Joshua Mallay (PSU) presents "Temporal Evolution of Atmospheric Aerosol Properties across the Eastern United States." (Not pictured: Mentors Thomas Eck (618/UMBC) and Pawan Gupta (GSFC/618).) Carson Turner and Allie Collow stand on either side of their poster which is on a gray posterboard.

Carson Turner (Univ. of Wyoming, OSTEM) and Allison Collow (610.1/UMBC) present "Evaluation of Aerosols in GEOS-CAM."
