sun.spct

sun.data

A dataset containing the wavelengths at a 1 nm interval and the
 corresponding spectral (energy) irradiance and spectral photon irradiance.
 Values simulated for 22 June 2010, near midday, at Helsinki, under partly
 cloudy conditions. The variables are as follows:

datasets

Definitions of classes, methods, operators and functions for use
in photobiology and radiation meteorology and climatology. Calculation of
effective (weighted) and not-weighted irradiances/doses, fluence rates,
transmittance, reflectance, absorptance, absorbance and diverse ratios and
other derived quantities from spectral data. Local maxima and minima: peaks,
valleys and spikes. Conversion between energy-and photon-based units.
Wavelength interpolation. Astronomical calculations related solar angles and
day length. Colours and vision. This package is part of the 'r4photobiology'
suite, Aphalo, P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.
