SimNDVI: NDVI simulation

In Ecohydmod: Ecohydrological Modelling

Description

This function simulates the NDVI based on soil moisture and vegetation parameters. Numerical solution.

Usage

SimNDVI(s, sw, sstar, kA, kR, Nmax, Nmin, N0)

Arguments

s	A vector with soil moisture
sw	Soil moisture at wilting point
sstar	Soil moisture below field capacity point
kA	Constant of assimilation
kR	Constant of respiration
Nmax	Maximum NDVI of the vegetation
Nmin	Minimum NDVI of the vegetation
N0	Initial condiction of NDVI. If it is missing, the average of Nmax and Nmin will be used

Examples

rain = 10 * RainPoisson(ndays = 365, lambda = 0.05, alpha = 0.60)
s = swb_f(R = rain, Rstar = 3, Emax = 5, Ew = 0.5, Ks = 2000, b = 4.38, Zr = 400,
n = 0.5, sh = 0.01, sw = 0.10, sstar = 0.25, s0 = 0.10, nsteps = 48, gr = T)[,3]
NDVI = SimNDVI(s, sw = 0.10, sstar = 0.35, kA = 0.064, kR = 0.011,
Nmax = 0.93, Nmin = 0.26, N0 = 0.5)
