We are pleased to present the Virtual Special Issue on Atmospheric Chemistry Research put together jointly by ACS Earth & Space Chemistry Associate Editor V. Faye McNeill and JPA A’s Senior Editors Andrew Orr-Ewing and Franz M. Geiger. Brush up on exciting papers published in the two journals over the past couple of years and perhaps use the collection as a roadmap for preparing or updating an upper level undergraduate/graduate course in atmospheric chemistry. Enjoy!
