Because of the great environmental significance of stratospheric ozone, and to support continuing research at the Antarctic Southern Hemisphere stations, the development of the 1991 ozone hole was monitored using data from the Nimbus-7 Total Ozone Mapping Spectrometer (TOMS) instrument, produced in near-real-time. This atlas provides a complete set of daily polar orthographic projections of the TOMS total ozone measurements over the Southern Hemisphere for the period August 1 through November 30, 1991. The 1991 ozone hole developed in a manner similar to that of the 1987, 1989, and 1990 holes, reaching a comparable depth in early October. However, the 1991 ozone hole filled far more rapidly than in 1987 or 1989, and nearly 4 weeks earlier than in 1990.
