While tropospheric ozone is only about 10% of the total amount of ozone present in the Earth atmosphere, it is nevertheless exceedingly important for the multiple roles it plays. However, the global height resolved distribution of ozone in the troposphere is largely unknown. The launch on July 15, 2004, of NASA's third of the Earth Observing System (EOS) series, the Aura observatory, carried with it the Tropospheric Emission Spectrometer (TES). This cooled infrared Fourier transform spectrometer was designed and built by JPL to provide the first global data sets of height profiles of tropospheric ozone. This talk will describe some of the new results and insights that utilize TES measurements. Topics will include transport of biomass burning emissions, the role of lightning in the ozone budget of the upper troposphere, the use of satellite data to aid in building urban air pollution budgets, quantifying the greenhouse impact of tropospheric ozone, and how water vapor isotope measurements add to our understanding of the global hydrological cycle. Tropospheric sensitivity has been limited with past and present remote sensing measurements. Looking to the future, we are characterizing the sensitivity of remote sensing measurements that combine wavelengths from the visible through the infrared, which potentially have sensitivity into the boundary layer, and are applicable to ozone, CO, SO2, CH4, CO2, as well as aerosols and clouds. The science benefit of this approach and a potential instrument design to achieve this will be discussed.
