(d) DMS-Aerosol Connections, contd. ACE(Aerosol Characterization Experiment)-1 MATCH MODEL PREDICTIONS: Comparison to Discoverer DMS Grey Shading=MATCH grid /ACE-1 point observation MIS-MATCH error Comparison to Discoverer SO2 Comparison to Cape Grim DMS Comparison to Macquarie Island DMS Comparison to Aircraft (RMBL) Flight averages Errors bars: Mis-match (model) & Trajectory Interpolation (model) & Standard Deviation (obs) MEASUREMENT SYSTEMS AND ESTIMATION A. In Situ measurements: Surface networks (e.g. NOAA/CMDL, AGAGE, etc.) − real time (CO, CH4, N2O, O3, halocarbons, etc.) − flasks (CO2, CH4, N2O, hydrocarbons, etc.) Balloon networks − real time (O3, H2O) − flasks (stratospheric halocarbons, etc.) Aircraft campaigns (e.g. NASA-GTE) - real time (O3,etc.) − flasks (hydrocarbons, etc.) B. Remote Sensing measurements: Satellite platforms − NASA (UARS, etc., stratosphere) − MOPPITT (CH4, CO, troposphere) − Downward or limb scan viewing Aircraft platforms − Ozone, aerosols, etc. Surface platforms − NDSC (stratosphere) Image courtesy of AGAGE.
