Increasing the Forest Fire and the Tropospheric Ozone Concentrations over Borneo Island Indonesia Based on 10 Years of Analysis Data

Tropical rainforest on the Borneo Island Indonesia is one of the lungs of the world. It plays a critical role in cleaning the air and stabilizes the climate system. Destroying of tropical rainforest will have a broad impact on compositions of atmosphere and strengthen the influence of climate change. This paper reveals an increasing the forest fire during the El Niño event and the tropospheric ozone concentrations over Borneo Island. The result shows that index correlation between number of forest fire and tropospheric ozone concentrations is 0.7. Increasing the ozone concentration on tropospheric layer occur at height 800 – 700 mb. The tropospheric low-level inversion has significant factor on this increasing. The average of tropospheric ozone concentration is 0.04 ppm and there is no seasonal variation due to monsoonal winds but its concentrations will increase three times than its average (0.12 ppm) when heavy forest fires happened due to El Niño impact.
