  1. Tropospheric Emission Spectrometer (TES) observations during the 2006 El Niño October 2005 October 2006 J.A. Logan, Harvard CO (ppb) • Drought in Indonesia from the 2006 El Niño caused major fires emitting pollutants like CO • CO over Indonesia was almost twice as high in October 2006 as in 2005 (above) • 2006-2005 difference plots show the relationship between CO, O3 and water vapor (below) Decreased water vapor over Indonesia (right) results from convection shifting to the Pacific during El Niño. CO from the fires (left) and shifts in convection both contribute to elevated ozone over Indonesia (center). TES has the first data set to show temporal changes in CO, O3, and H2O, providing a useful test for models. ΔCO (ppb) Δozone (ppb) ΔH2O (ppth)
