ACT-America

The Atmospheric Carbon and Transport–America (ACT-America) project was a NASA Earth Venture Suborbital-2 mission to study the transport and fluxes of atmospheric carbon dioxide and methane across three regions in the eastern United States. Flight campaigns measured the transport of greenhouse gases by continental-scale weather systems. Ground-based measurements of greenhouse gases were also collected. Project goals included better estimates of greenhouse gas sources and sinks, which are required for climate management and for prediction of future climate.
