Abstract

Satellite measurements of the distribution of the global atmospheric CO₂ would get its continuous change. The atmospheric infrared sounder (AIRS) enables us to monitor the global distribution and transport of middle troposphere CO₂. Mount merapi is an active strato-volcano located on the border between central java and yogyakarta, indonesia. The AIRS data were acquired from 15th october to 15th november in 2008, 2009 and 2010 to monitor the temporal-spatial distribution of erupted CO₂ from the volcano. Mid-tropospheric CO₂ concentration would increase gradually and reach its peak in one day from eruption. The dispersal range of erupted CO₂ was -7.540831±7.5°, 110.444817±5° in the graticules centering around gunung merapi. Having a high correlation with the eruptions, the mid-troposphere CO₂ concentration of 2010 showed different trend comparing with 2008 and 2009 trend. The 4-day CO₂ concentration data of 2010 over the volcano tended to increase by 2.9 ppmv and 4.1 ppmv comparing with that of 2009 and 2008 respectively. These observations provide the evidence that extensive release of CO₂ occurs during the volcano eruption time and using the AIRS CO₂ products to monitor the temporal-spatial distribution of erupted CO₂ from volcanoes is possible.
