In DrylandEcology/rSW2funs: Functions for Derived Variables from SOILWAT2 Simulations

Determine resilience & resistance classes (sensu Chambers et al. 2014) based on soil moisture and soil temperature regimes

Description

Determine resilience & resistance classes (sensu Chambers et al. 2014) based on soil moisture and soil temperature regimes

Usage

calc_RRs_Chambers2014(Tregime, Sregime, MAP_mm)

Arguments

Tregime	A named numeric vector. The soil temperature regime “STR” element of the return object of calc_SMTRs.
Sregime	A named numeric vector. The soil moisture regime “SMR” element of the return object of calc_SMTRs.
MAP_mm	A numeric value. The mean annual precipitation in millimeters.

Value

A named numeric vector of 0s and 1s indicating the matching resilience and resistance class. Note: All elements may be 0 if the input soil moisture/temperature regimes are not covered by Chambers et al. 2014.

Examples

# Calculate soil moisture and soil temperature regimes
sw_in <- rSOILWAT2::sw_exampleData
sw_out <- rSOILWAT2::sw_exec(inputData = sw_in)
SMTR <- calc_SMTRs(sim_in = sw_in, sim_out = sw_out)

# Determine average across years and set aggregation agreement level
Tregime <- colMeans(SMTR[["STR"]]) >= 0.9
Sregime <- colMeans(SMTR[["SMR"]]) >= 0.9

# Calculate resilience and resistance categories
clim <- rSOILWAT2::calc_SiteClimate(
  weatherList = rSOILWAT2::get_WeatherHistory(sw_in)
)
calc_RRs_Chambers2014(Tregime, Sregime, MAP_mm = 10 * clim[["MAP_cm"]])
