The Atmospheric Carbon and Transport - America (ACT-America) investigation was a NASA Earth Venture Suborbital 2nd funding cycle (EVS-2) project. Five ACT-America deployments occurred between July 2016 and July 2019. The investigation focused on the study of atmospheric carbon dioxide and methane transport over the midwest, mid-atlantic, and southern US specifically to examine how greenhouse gases are transported by weather patterns in various seasons. The main objectives were to quantify and reduce atmospheric transport uncertainties, to improve regional-scale and seasonal estimates of carbon dioxide and methane fluxes, and to evaluate the sensitivity of OCO-2 measurements. The results address three primary sources of uncertainty in carbon dioxide and methane sources and sinks – transport error, prior flux uncertainty and limited data density. Various greenhouse gas measuring instruments flew onboard the King Air B-200 and the C-130 Hercules aircraft in addition to data collected by various tower networks.
