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:
Format
A source_spct object and a data.frame, each with 511
rows and 3 variables
An object of class data.frame with 508 rows and 3 columns.
Note
Package 'photobiologySun' contains data sets for the daylight spectrum under different conditions in and outside vegetation, stored in objects of these same classes, ready to be used with package 'photobiology'.
