AAFMERGED

For 30 years, the U.S. Department of Energy (DOE) Office of Science supported an instrumented Gulfstream-159 (G-1) aircraft for atmospheric field campaigns. Data from the final decade of G-1 operations were archived by the Atmospheric Radiation Measurement (ARM) user facility Data Center and made publicly available at no cost to all registered users. To ensure a consistent data format and to improve the accessibility of the ARM airborne data, an integrated data set was recently developed covering the final six years of G-1 operations (2013 to 2018). When complete, the full integrated data set will include data collected from 236 flights (766.4 hours), covering the Arctic, the U.S. Southern Great Plains, the U.S. West Coast, the Eastern North Atlantic, the Amazon Basin in Brazil, and the Sierras de Córdoba range in Argentina. These comprehensive datastreams will provide much-needed insight into spatiotemporal variability of thermodynamic quantities and aerosol and cloud states and properties for addressing essential science questions in earth system process studies.
