Abstract

Two new products [1,2] have been developed from the TOMS (Total Ozone Mapping Spectrometer) satellite instrumental to resolve pollution in the tropics and mid-latitudes. The modified-residual technique [3, 4] uses v. 7 TOMS total ozone and is applicable to tropical regimes in which the wave-one pattern in total ozone is observed. The second method, the TOMS-Direct method [5] is a new algorithm that uses TOMS radiances to extract tropospheric ozone in regions of constant stratospheric ozone. In these regions, tropospheric ozone displays the high mixing ratios seen in urban pollution episodes. Electronic versions of daily and 9-day averaged modified-residual tropospheric ozone ("TTO" data and images) for the Nimbus 7/TOMS observing period (1979-1992) and the Earth Probe/TOMS (8/1996-2000) are available at 1-degree latitude x 1.25-degree longitude resolution at http://metosrv2.umd.edu/~tropo. The 1998-2000 TTO (tropical tropospheric ozone) column amounts have been validated using data from a network of ozonesconde stations [6, 7]; http://code916.nasa.gov/Data_services/shadoz.
