spwb_maximumTranspirationRatioPlot: Maximum transpiration vs. LAI

Description

Builds a curve of maximum transpiration (Tmax) over potential evapotranspiration (ETP) for increasing leaf area index (LAI) values.

Usage

spwb_maximumTranspirationRatioPlot(x, soil, meteo, latitude, elevation, slope, aspect, 
                                   ndays = 100, 
                                   LAI_seq = c(0.1, 0.25, seq(0.5, 10, by = 0.5)))

Arguments

x

An object of class spwbInput.

soil

A list containing the description of the soil (see soil).

meteo

A data frame with daily meteorological data series.

latitude

Latitude (in degrees). Required when using the 'Sperry' transpiration mode.

elevation, slope, aspect

Elevation above sea level (in m), slope (in degrees) and aspect (in degrees from North). Required when using the 'Sperry' transpiration mode.

ndays

Number of days to subset for curve building.

LAI_seq

Sequence of stand LAI values to be tested.
