Pronounced enhancements of total and tropospheric O3 were observed with a Brewer spectrophotometer and ozonesondes at Watukosek, Indonesia in October 1997 (Fujiwara et al., 1999). The integrated tropospheric O3 increased from 20 DU to 55 DU in October 1997. On October 22, 1997, the O3 concentrations were more than 50 ppbv throughout the troposphere and exceeded 100 ppbv at several altitudes. The authors conclude that the enhanced levels of O3 measured in October 1997, resulted from O3 precursors, produce during the fires and released into the atmosphere. 

Brewer and Field Spec spectrophotometers and pyranometers) and LOWTRAN 7 code (6) results. In this way, this model can be also a useful tool for a wide range of applications in Visible and Infrared spectra, mainly for data validation and for the simulation of the radiation changes due to changes in the atmospheric chemical composition.
