In honor of AIP's newest Member Society, the American Meteorological Society, we feature atmospheric physics. Researchers in the field have utilized such intriguing scientific equipment as sounding rockets, weather balloons, and a cloud chamber that can produce "man-made snow." It was Benjamin Franklin who proposed and later conducted the first kite experiment, trying to understand the mysterious ways of lightning and atmospheric electricity. Later, scientists would begin expeditions as far as Antarctica to gain insights into atmosphere and climate conditions. An expedition on conducting upper atmosphere water vapor studies under the sponsorship of the National Science Foundation is highlighted in this month's collection.
