Continental‐Scale Geographic Trends in Barometric‐Pumping Efficiency Potential: A North American Case Study

Abstract

Barometric pumping is a natural process that drives gas transport from underground to the ground surface as the atmospheric pressure fluctuates. When barometric pressure increases, it pushes atmospheric air into the subsurface. Then as barometric pressure decreases, it pulls the subsurface gases up toward the surface. In effect, along with other processes such as thermal convection (
