Welcome to the Total Ozone Mapping Spectrometer (TOMS) home page. The images and data contained here are provided by the Ozone Processing Team (OPT) located in Code 916 at NASA's Goddard Space Flight Center. On these pages you will find general information on ozone satellite retrieval and our group. Information about Earth Probe/TOMS (which is presently scheduled for launch sometime this year), Meteor-3, and Nimbus-7 can be accessed by clicking on their images above.

Here are a few thing things of general interest:

• The TOMS
  • Includes information and SO2 images from recent volcanic eruptions
• The Code 916 FAQ List
• The Code 916 Glossary of Terms
• A NASA fact sheet on ozone and why we care about it.
• A QuickTime movie showing the 1994 ozone hole event as seen from M3/TOMS (851 Kb) [[
  • Note: You need a QuickTime player on your system to view this movie. Macintosh (sys 7+), SGI(sys 5.3), and PCs running Apple's QuickTime for Windows can view these types of movies easily.
• A GIF image showing the ozone hole from 1979-1994. (Note: 1981 is not shown due to image space constraints) (240K)
• A plot showing the average ozone hole size from 1979-1994. (9K)
• A plot showing the ozone hole minima from 1979-1994. (12K)
• How to obtain TOMS Ozone CD-ROMS

Here are some ozone related press releases:

• The 1994 ozone hole
• The link between man-made chemicals and ozone depletion
• Successful US-Russion ozone-monitoring mission appears over

Since Meteor-3/TOMS is no longer operating, there will be no operational TOMS instruments until the launch of Earth Probe TOMS (mid summer at the earliest). Until then, the only available daily, full-coverage global ozone data is from NOAA's TOVS. (Note: Since TOVS data is produced by NOAA they are responsible for its quality.)
