Atmospheric chemistry is strongly affected by biomass burning and urban pollution. Through photochemistry, high concentration of ozone is produced in the troposphere. High concentration of ozone precursors such as NO_x, CO, hydrocarbons are produced during the annual biomass burning seasons (farming seasons) in the tropics. This production of ozone precursors is enhanced by El Nino events. Also responsible for the production of high concentration of ozone precursors are urban pollution sources such as industrial plants, automobiles and domestic heating systems. In this respect, due to the availability of the Global Ozone Monitoring Experiment (GOME) remote sensing data, the FUll Retrieval Algorithm Method (FURM) is used to retrieve ozone profiles in the GOME UV-wavelength bands for 1997 and 1998 over Watukosek (Indonesia) and Hohenpeißenberg (Germany). Due to the availability of SHADOZ (Southern Hemisphere Additional Ozonesondes) and the DWD (Deutsche Wetterdienst) ozone sonde in-situ measurements, FURM retrieved ozone vertical columns and profiles are compared with Sonde vertical columns and profiles to check for the efficacy of the FURM algorithm. The KNMI (Royal Dutch meteorological institute) Climatology was used for the FURM implementation.
