We thank the many scientists involved in red-rain case studies for their data and, in particular, Dr. Turkan Özsoy of Mersin University, Turkey, for colored-rain data for Turkey. We greatly appreciate a reviewer's suggestion to conduct the HYSPLIT back-trajectory simulations, as well as additional suggestions by the editor.
