Code for analysis published as Global patterns of water storage in the rooting zones of vegetation.

The name of this repo derives from Mass Curve Technique, as referred to by Gao et al., 2014, the paper that stood at the very beginning of this analysis.

Important files

• workflow.Rmd: Outlines all steps for the global analysis. Implements plotting of published figures. Computation-heavy step are implemented for cluster computing (using files rscript_*.R and submit_*.sh).
• rsip.Rmd: Implements all steps for comparison of global rooting depth estimates against observations, and additional analyses of observations.
• eval_et.Rmd: Implements the evaluation of different remote sensing-based ET products against observations from FLUXNET.
• rsofun_rsip_mct.Rmd: Additional rsofun (SPLASH) simulations at RSIP site locations and visualisations, to test method for diagnosing S0.
• rsip_tga.Rmd: Trait gradient analysis on rooting depth data
• create_suppl_info.Rmd: Additional visualisations of method for diagnosing S0.

Key analysis steps:

• ET conversion to mass units: R/convert_et.R
• Snow mass balance: R/simulate_snow2.R
• Cumulative water balance algorithm: R/mct2.R (same as implemented by the cwd R package)
• Extreme value distribution fitting: R/get_plantwhc_mct_bysite.R
• Soil water holding capacity using pedo-transfer functions: R/calc_soilparams.R
• Diagnosing $S_0$ and "flattening" relationships from SIF and EF vs. CWD: R/calc_cwd_lue0_v2.R
