MODEL RELEASED. Stratospheric ozone research. Technicians and European Union (EU) Commissioner Philippe Busquin (in white hat) release a balloon to measure stratospheric ozone over the Arctic. This gas filters most of the harmful ultraviolet radiation from sunlight. Ozone levels decline over the Arctic each spring as it is destroyed by chlo- rine released by human activities. This work was part of a joint project by NASA and the EU to look at the amount and rate of stratospheric ozone depletion. Numerous balloon releases took place between November 1999 and March 2000.
