Tropospheric column ozone (in Dobson units) determined using the difference between the total column ozone measured by OMI and stratospheric ozone measured by the MLS instrument on the Aura satellite. A transport model was used to increase the horizontal resolution of the MLS-derived stratospheric column ozone. Global depictions for July and October 2008 show streams of tropospheric ozone crossing oceans, an important result for understanding both climate and air quality. Credit: M. Schoeberl and J.
