A TOMS-Based View of Tropical Tropospheric Ozone (OTTO) From Large Fires Associated with the 1997-1998 El NinoSince the launch of Earth-Probe TOMS in July 1 996, we have been producing tropical tropospheric ozone (TTO) maps (10S - 10N), in gridded format, l x 2 degrees, in near-real time. These images, along with images from the full ADEOS-TOMS record of TTO (Sept. 1996 - May 1997) can be viewed on a homepage: http://metosrv2.umd,edu/-tropo). The TTO maps, based on the modified-residual method of Hudson and Thompson [1998], have been validated using ozonesondes from Ascension (8S, 15W), Nairobi (2S, 36E) and American Samoa (14S, 171W). The fires associated with El Nino-induced dryness are exhibited regionally as high tropospheric ozone column (> 60 Dobson Units) with high absorbing aerosol (smoke) signal in TOMS [J. R. Herman, personal communication, 1998]. Episodes of high TTO in 1997-98 will be shown. Regional TTO over Indonesia during the 1997-98 period will be highlighted and comparisons will be made with TTO in that region taken from the 1979-92 Nimbus/TOMS TTO record.
