As of March 3, 2010 MOPITT hascompleted ten years of operation measuring carbon monoxide (CO) over the planet and the measurementscontinue. These measurements have demonstrated the changes of CO in both space and time and shown aplanet with very large variations in concentrations depending upon events and circumstances. Two of themajor conclusions are that CO varies over time and space in such a manner that it is almost impossible todescribe an “average year” and that pollution is always a global issue rarely a purely regional one.During the mission there have been a number of challenges, both scientific and engineering, that have beensuccessfully overcome to bring the instrument to the present time and even after 10 years in orbit significantimprovements to the datasets are still being made.MOPITT was provided to the Terra spacecraft by the Canadian Space Agency and was built by COMDEVof Cambridge, Ontario. Data processing is performed by the MOPITT team at the National Center forAtmospheric Research, Boulder, CO. Instrument control is by the team at the University of Toronto.Observations 2.2 ID:4510 08:45Next Generation Remote Sensing of Ozone: An Assessment of Tropospheric SensitivityAnnmarie Eldering 1 , Kelly Chance 2 , Robert Chatfield 3 , David Edwards 4 , Joanna Joiner 5 , SusanKulawik 1 , Thomas Kurosu 2 , Xiong Liu 2 , Vijay Natraj 1 , Ken Pickering 6 , Robert Spurr 7 , Helen Worden 4 ,Kevin Bowman 11 Jet Propulsion Laboratory/ California Institute of Technology2 Smithsonian Astrophysical Observatory3 NASA Ames4 National Canter for Atmospheric Research5 NASA Goddard6 University of Maryland, College Park7 RT Solutions, IncContact: Annmarie.Eldering@jpl.nasa.govWe are systematically characterizing the sensitivity that is possible and needed for the next leap forward inremote sensing of ozone, with an emphasis of reaching lower into the troposphere. Space basedmeasurements of ozone have been made for years in the ultraviolet and visible region, and separately, in theinfrared. Although we have a long record of measurements, we are still limited in measurements relevant toboundary layer air pollution.Making measurements from a geostationary satellite, such as GEO-CAPE, would be a huge benefit, allowingmeasurements on hourly timescales, which would let us capture the rapid diurnal changes of air pollutionspecies. In additional to more frequent measurements, we need ozone measurements that are more sensitiveto the lower layers of the atmosphere (lowest 2 kilometers).
