ARID is one of the two scoping studies funded by NASA in 2023 to identify the scientific questions and develop the initial study design and implementation concept for a new NASA Terrestrial Ecology field campaign. This report emphasizes a prioritized research agenda and an initial implementation plan, focusing on the western U.S. to deepen our understanding of national dryland processes and resources. ARID is also leveraging an extensive network of international sites and collaborators in southern Africa, Australia, Mexico, and South America. This global approach facilitates the evaluation, monitoring, and forecasting of drylands worldwide, ensuring a coordinated effort to address and inform solutions for the challenges facing these critical ecosystems. ARID will use cutting-edge approaches to address four Science Themes: 1) Climate Variability and Drought, 2) Ecosystem Structure, Function, and Biodiversity, 3) Carbon Cycle Interannual Variability and Long-Term Trends, and 4) Social-Ecological Systems. The scoping study performed extensive outreach, conducting over 160 meetings and events, which translated to the ARID science plan being co-created with a wide range of contributors and perspectives, including remote sensing, modeling, and dryland scientists; Tribal Nations; and diverse federal entities. This report outlines a targeted plan to deploy field and NASA airborne instruments to vastly augment data derived from satellite observations that, when joined, will substantially advance quantification of drylands' large and changing role in the Earth system.}, publisher={ORNL Distributed Active Archive Center}, author={Reed, S.C. and Feldman, A.F. and Hanan, N.P. and Moore, D.J.P. and Ojima, D.S. and Smith, W.K. and Wessels, K. and Amaral, C. and Babst, F. and Biederman, J. and Litvak, M.E. and MacBean, N. and Poulter, B. and Scott, R.L. and Babst-Kostecka, A. and Fu, Z. and Green, J.K. and Kokaly, R.F. and Swap, R.J. and Serbin, S.P. and Tucker, C.J. and Wang, L. and Watts, J.D. and Wolfe, G.M. and Flores, A. and Leaf, J.R. and Washington-Allen, R. and Prentice, K. and Kachergis, E. and Reyes, J. and Ryan, J. and SanClements, M. and Loescher, H. and Leidner, A. and Swetnam, T. and Cook, B.}, year={2025}, language={en}, }
