Airborne Arctic Stratospheric Expedition (AASE)

NASA is addressing the crucial scientific issue of global ozone depletion. A major airborne campaign was planned and executed in August and September of 1987 to study the sudden and unanticipated decrease observed in the abundance of ozone over Antarctica in the Austral spring since 1979. Results from that study have provided data which directly implicate man-made chemical compounds, chlorofluorocarbons, in the enormous ozone loss over this remote region in the southern hemisphere.
