PG: Constructor of PG weighted waveband

Description

Plant growth BSWF of Flint and Caldwell

Usage

PG(norm = 300, w.low = 275, w.high = 390)

Value

a waveband object wavelength defining wavelength range, weighting function and normalization wavelength.

Arguments

norm

normalization wavelength (nm)

w.low

short-end boundary wavelength (nm)

w.high

long-end boundary wavelength (nm)

Details

The mathematical formulation included by Flint and Caldwell (2003) as an appendix is used. While this formulation is consistently used, the range of wavelengths over which it has been applied has varied. We use the approach of the NSF UV network and extrapolate up to 390 nm. The widely used simulation program TUV uses, instead, 366 nm as the boundary, which makes a significant difference to the computed irradiance values in sunlight.
