Résumé
This data set is a supplement for: Longo, M., S. S. Saatchi, M. Keller, K. W. Bowman, A. Ferraz, P. R. Moorcroft, D. Morton, D. Bonal, P. Brando, B. Burban, G. Derroire, M. N. dos-Santos, V. Meyer, S. R. Saleska, S. Trumbore, and G. Vin- cent, 2020: Impacts of degradation on water, energy, and carbon cycling of the Amazon tropical forests. J. Geophys. Res.-Biogeosci., 125 (8), e2020JG005 677, doi:10.1029/2020JG005677. This data set contains the following files (which should be all downloaded and uncompressed in the same root directory): 00_SiteLidar.zip – R scripts to process forest inventory plots and Airborne LiDAR point clouds. Sub-directories contains a directory Template, which should be copied for each site for which data are to be processed. 01_LidarSynthesis.zip – R scripts to fit the statistical models of aggregated properties, and to evaluate both the statistical model and the prediction of Airborne LiDAR profiles to be used to initialize ED-2.2. 02_model_eval.zip – R scripts to compare the ED-2.2 model output and evaluate the model against tower observations. 03_degrad_mtr – R scripts to visualize the ED-2.2 simulation results. InputData – Miscellaneous data to be used by the scripts. Util – Additional R scripts Rsc – Mostly R functions, which may be called by other R scripts OutsideLAS – List of plots that were not fully overlapped by the Airborne LiDAR surveys GenMERRA2_ED2 – Utility scripts to process MERRA-2 to generate the met drivers needed by ED-2.2 GenMSWEP2_ED2 – Utility scripts to process MSWEP-2.2 to generate the met drivers needed by ED-2.2 ED2IN_Config – list of ED2IN files used in the runs. To see the input data used for this analysis, load any of the objects available in 01_LidarSynthesis/01_eval_multivar, and look for the following structures: List of variables and units of data structure census[[1]], rlidar[[1]], and tchdat[[1]]. Variable Structure Description Units identifier census[[1]], rlidar[[1]], tchdat[[1]] Plot identifier. This always has the site identifier (see below), the area within each site, the nominal year of the campaign, the unique sub-plot ID (Pxx_Byy for rectangular plots, and Txx_Pyy for long transects)
