Determining accurate velocity measurements from observations of the Sun is vital importance to solar physicists who are studying wave dynamics in atmosphere. Weak chromospheric absorption lines, due dynamic events atmosphere, often consist multiple spectral components. Isolating these components allows for field and quiescent regimes be studied independently. However, isolating such particularl...

Geologic sequestration in depleted oil reservoirs, saline aquifers, etc. has been proposed as an effective way to stabilize the concentration of CO2 in the atmosphere and thus mitigate its effect on global climate change. We have developed a massively parallel 3-D reservoir simulator PFLOTRAN for modeling supercritical CO2 sequestration in geologic formations based on continuum scale mass and e...
