The Grimsvotn volcano continues to erupt at the same levels as it has since Saturday, the eruption is reportedly “much bigger and more intensive” than Eyjafjallajökull eruption last year and 10 times bigger than Grimvotn’s eruption in 2004. However, it is not expected to have nearly the same effect as the Eyjafjallajökull eruption (and the 2004 Gromsvotn eruption had little effect). Why?
The scientists used a general circulation model known as ModelE (developed at NASA’s Goddard Institute for Space Studies, New York). The model calculates ocean-atmosphere coupling effects in addition to allowing varying aerosol inputs.
The initial input for the simulation was 5 teragrams (megatons) of black carbon particles injected into Earth’s upper troposphere. This is the estimated result of the surface detonation of 100 Hiroshima-size bombs (each equivalent to 15K tons of TNT).
