TOMS Ozone
This image displays global ozone from the last official data collection day of the TOMS instrument, Dec. 30, 2005. These images enable scientists throughout NASA, the US Government, and the international science community to better understand the relationship between atmospheric ozone distribution and the factors that alter it.
