Acknowledgments
The paper’s findings are based on the data collected at the Barrow Atmospheric Observatory. I thank the Earth System Research Laboratory (ESRL), Global Monitoring Division (GMD), of the National Oceanic and Atmospheric Administration (NOAA) for supporting the operations of this observatory. I am also grateful to NOAA’s National Weather Service and National Centers for Environmental Information for their stewardship of the PABR temperature data. The unit root conclusions rely partly on the hourly temperature data reported by the Syowa observatory in Antarctica. I am thankful to the National Institute of Polar Research in Japan for supporting the operations of this observatory. I am also grateful for NASA’s CERES/ARM Validation Experiment (CAVE) stewardship of the data from this observatory. Earlier versions of this paper were presented at the ESIPP/UCD weekly seminar and the ESRI/UCD policy conference. I thank the participants for their feedback. The research was also presented as an e-poster at the 2020 AGU Fall meetings in a session entitled, “Convergence Research in Climate Science: How to Move Beyond Disciplinary Silos.” I thank the participants of that session for their comments. I thank Jeffery Wooldridge, Nick Cox, and Maarten Buis for sharing their econometric insights. I thank Rick Thoman for sharing his meteorological insights. I also thank Chris St. Cyr and Dina Tady for their candid comments on an earlier draft. Any errors are the full responsibility of the author.
