The ORNL DAAC recently released the ACT-America Campaign Catalog developed by Pal, S., and K.J. Davis (2021):
The ACT-America Campaign Catalog provides comprehensive information about the five airborne campaigns of the Atmospheric Carbon and Transport (ACT-America) project. A total of 121 research flights were conducted within the five six-week seasonal campaigns by each of two instrumented aircraft platforms. The Catalog compiles flight details conducted during Summer 2016, Winter 2017, Fall 2017, Spring 2018, and Summer 2019 across three regions of the eastern and central United States. Included are flight dates, regions, objectives, weather conditions, instrument status, aircraft flight paths, detailed weather reports, and summary measurement figures.
The ACT-America mission spanned five years and included field campaigns covering all four seasons over central and eastern regions of the United States. ACT-America's objectives were to study the transport and fluxes of atmospheric CO2 and CH4. Two instrumented aircraft platforms, the NASA Langley Beechcraft B-200 King Air and the NASA Wallops Flight Facility's C-130 Hercules, were used to collect high-quality in situ measurements across a variety of continental surfaces and atmospheric conditions. At times they flew directly under Orbiting Carbon Observatory-2 (OCO-2) overpasses to evaluate the ability of OCO-2 to observe high-resolution atmospheric CO2 variations. The C-130 aircraft was also equipped with active remote sensing instruments for planetary boundary layer height detection and column greenhouse gas measurements.
