Tropical Tropospheric Ozone: New Insights from Remote Sensing, Sondes and Field StudiesThis talk will summarize our recent research in tropical tropospheric ozone studies in the field and from space. New tropospheric ozone and aerosol products from the TOMS (Total Ozone Mapping Spectrometer) satellite instrument will be highlighted (Hudson and Thompson, 1998; Thompson and Hudson, 1999). These are suitable for studying processes like ozone pollution resulting from biomass fires, seasonal and interannual variations and trends. Archived maps of tropospheric ozone over the tropics, from the Nimbus 7 observing period (1979-1992) are available in digital form at our website: http://metosrv2.umd.edu/-tropo. Real-time processing of TOMS data has produced images of tropical tropospheric ozone (TTO) since early 1997, using Earth-Probe TOMS; these maps are also available on the homepage. The need for validation data for TTO maps has led to establishment of the NASA/NOAA-sponsored SHADOZ (Southern Hemisphere Additional Ozonesondes) network, from which a 2-year record of high-quality ozonesonde data can be obtained: (http://hyperion.gsfc.nasa.gov/Data-services/Shadoz/shadoz-hmpg2.htrnl). Examples will be shown, along with ozonesondes from the January-February 1999 Aerosols-99 cruise of the R/V Ronald H Brown from Virginia to Cape Town, South Africa.
