sun_hourly_june.spct: Ground level spectral irradiance at hourly intervals
In photobiologySun: Data for Sunlight Spectra

Description Usage Format Details Note Author(s) References

Datasets containing the wavelengths at 1.0 nm interval and tabulated values spectral irradiance for the sun for 22 to 24 June 2010 in Helsinki, Finland.

1	sun_hourly_june.spct

A data frame with 29464 rows (293 nm to 800 nm at 1 nm interval) and 3 variables.

The variables are as follows:

w.length numeric (nm)
s.e.irrad numeric (W m-2 nm-1)
UTC POSIXct (UTC date and time)

The data set includes NAs for missing night-time spectral irardiance values.

A summary of these data has been published in the article by Morales et al. (2013). The simualtion methods has been described in Lindfors et al. (2009).
