description: Reproducible workflow of the article <strong>Migliavacca et al., The three major axes of terrestrial ecosystem function. Nature. https://doi.org/10.1038/s41586-021-03939-9. </strong>The object contains the scripts to reproduce the analysis and identify the key axes of terrestrial ecosystem function. The input dataset (InputDataMigliavacca2021.csv) contains ecosystem functional properties (EFP), climate and structural variables, as well as ancillary information about the sites. <strong>List of input variables:</strong> * SITE_ID --&gt; Site Identifier<br> * PFT --&gt; Plant Functional Type definition (for the legend plese refer to the manuscript).<br> * KoeppenGeiger --&gt; Koeppen Geiger Climate Classification.<br> * latitude --&gt; site latitude, geographic coordinates as decimal fractions of a degree.<br> * longitude --&gt; site longitude, geographic coordinates as decimal fractions of a degree.<br> * dataset --&gt; dataset from which the site data were downloaded (Lathuile or FLUXNET2015) <br> * TZ --&gt; Time zone<br> * nyears --&gt; Number of years for each site<br> * uWUE --&gt; underlying Water Use Efficiency [gC kPa^0.5 kgH2O-1]<br> * ETmax --&gt; maximum evapotranspiration [mm]<br> * GSmax --&gt; maximum surface conductance [m s-1]<br> * G1 --&gt; ecosystem scale stomatal slope [kPa^0.5]<br> * EF --&gt; mean daytime evaporative fraction (LE/H+LE) computed in the growing season [-]<br> * EFampl --&gt; mean daytime evaporative fraction (LE/H+LE) computed in the growing season [-]<br> * GPPsat --&gt; Gross Primary Productivity at light saturation [umol CO2 m-2 s-1]<br> * NEPmax --&gt; maximum net CO2 uptake of the ecosystem [umol CO2 m-2 s-1]<br> * Rb --&gt; Mean basal ecosystem respiration at reference temperature of 15 °C [umol CO2 m-2 s-1]<br> * Rbmax --&gt; Maximum basal ecosystem respiration at reference temperature of 15 °C [umol CO2 m-2 s-1]<br> * aCUE --&gt; Apparent Carbon Use Efficiency [-]<br> * WUEt --&gt; WUE based on transpiration (T) estimates [gC kgH2O-1] <br> * Nmass --&gt; ecosystem scale foliar nitrogen concentration [gN 100 g-1]<br> * LAImax --&gt; Maximum Leaf Area Index [m2 m-2]<br> * SWin --&gt; Mean incoming shortwave radiation [W m-2]<br> * Tair --&gt; Mean temperature [degree C]<br> * VPD --&gt; Mean Vapor Pressure Deficit [hPa]<br> * P --&gt; Mean annual precipitation [mm/year]<br> * CSWI --&gt; cumulative soil water index [-]<br> * Hc --&gt; Maximum vegetation height [m]<br> * AGB --&gt; Aboveground Biomass derived from the Globbiomass project [t DM ha-1] <strong>NOTES</strong>: <br> * The dimensions of the figures are not the same as in the article, this should be considered as an example for the workflow.<br> * The workflow requires REddyProc version 1.2.2. <br> * The folder contains two additional scripts: <br> * ExampleEFPextraction.R --&gt; example of flowchart to derive ecosystem functional properties (EFP) from FLUXNET data. We provide data from the site AT-Neu to test the code (we thank the PI Prof. Georg Wohlfahrt – University of Innsbruck - for the data)<br> * ExtractionEFPsLSM.R --&gt; This script calculate the ecosystem functional properties from land surface model runs in Migliavacca et al., 2021<br> * Land surface model runs are available as csv files. The readme file with the units for each model runs are reported in the folders:<br> For JSBACH "data/LSM/runs/JSBACH/README_JSBACH.rtf"<br> For OCN "data/LSM/runs/OCN/README_OCN.rtf"
