sun_hourly_june.spct: Ground level spectral irradiance at hourly intervals

Description

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.

Usage

sun_hourly_june.spct

Arguments

Format

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

Details

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.
