The 1997 El Ni?o impact on clouds, water vapour, aerosols and reactive trace gases in the troposphere, as measured by the Global Ozone Monitoring Experiment

摘要

The El Niño event of 1997/1998 caused dry conditionsover the Indonesian area that were followed by large scale forest andsavannah fires over Kalimantan, Sumatra, Java, and parts of Irian Jaya.Biomass burning was most intense between August and October 1997, and largeamounts of ozone precursors, such as nitrogen oxides, carbon monoxide andhydrocarbons were emitted into the atmosphere. In this work, we usesatellite measurements from the Global Ozone Monitoring Experiment (GOME)sensor to study the teleconnections between the El Niño event of 1997and the Indonesian fires, clouds, water vapour, aerosols and reactive tracegases (nitrogen dioxide, formaldehyde and ozone) in the troposphere.
