This data set provides atmospheric carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), and ozone (O3) concentrations collected during airborne campaigns conducted by the Atmospheric Carbon and Transport-America (ACT-America) project. ACT-America's mission spans 5 years and includes five 6-week field campaigns covering all 4 seasons and 3 regions of the central and eastern United States. Two instrumented aircraft platforms, the NASA Langley Beechcraft B200 King Air and the NASA Goddard Space Flight Center's C-130H Hercules, are used to collect high-quality in situ measurements across a variety of continental surfaces and atmospheric conditions. CO2, CO, and CH4 are collected with an infrared cavity ring-down spectrometer system (CRDS; Picarro Inc.). Ozone data are collected with a dual beam differential UV absorption ozone monitor (Model 205; 2B Technologies). Both aircraft host identical arrays of in situ sensors. Complete aircraft flight information including, but not limited to, latitude, longitude, and altitude are also provided.
