ACT-America: L2 In Situ Atmospheric CO2, CO, CH4, and O3 Concentrations, Eastern USA

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.
