Samples were collected from plots within the Dangermond Preserve, Sedgwick Reserve, and Carpinteria Salt March Reserve during the period of February 23, 2022 to September 27, 2022 for the 2022 NASA Surface Biology Geology (SBG) High Frequency Time series (SHIFT) campaign. The associated data package contains image scans used for the leaf area calculations as well as python processing code used to calculate the area. A comma-separated value (CSV) formatted file includes plot-level leaf area (cm2), wet weight (g), leaf mass area (LMA, g leaf dry mass per meter square), leaf water content (LWC, (wet weight - dry weight/wet weight, %)), chlorophyll fluorescence ratio (CFR), and chlorophyll content (CHL).}, publisher={ORNL Distributed Active Archive Center}, author={Chadwick, K.D. and Queally, N. and Zheng, T. and Cryer, J. and Vanden Heuvel, C. and Villanueva-Weeks, C. and Ade, C. and Anderegg, L. and Angel, Y. and Baker, B. and Boving, I. and Braghiere, R.K. and Brodrick, P. and Campbell, P. and Cushman, K.C. and Davis, F.W. and Dao, P.D. and Dibartolo, A. and Eckert, R. and Grant, K. and Heberlein, B. and Johnson, M. and Joutras, J. and Kibler, C. and Klope, M. and Kovach, K.R. and Kreisberg, A. and Lovegreen, P. and Maguire, A.J. and Mcmahon, C.A. and Miner, K. and Nickles, C. and Ochoa, F. and Ocón, J.P. and Ongjoco, A. and Ordway, E.M. and Park, M. and Pavlick, R. and Raiho, A.M. and Roberts, D.A. and Schimel, D.S. and Schneider, F.D. and Thompson, K. and Townsend, P.A. and Vermeer, E. and Vinod, N. and Zumdahl, K.}, year={2023}, language={en}, }
