R: Daily solar spectral irradiance (simulated)

sun.daily.spct {photobiology} | R Documentation

## Daily solar spectral irradiance (simulated)

### Description

A dataset containing the wavelengths at a 1 nm interval and the corresponding spectral (energy) irradiance. Values simulated for 2 June 2012, at Helsinki, under clear sky conditions. The variables are as follows:

### Usage

    sun.daily.spct

### Format

A `source_spct` object with 511 rows and 3 variables

### Details

- w.length (nm), range 290 to 800 nm.

- s.e.irrad (J d-1 m-2 nm-1)

- s.q.irrad (mol d-1 m-2 nm-1)

### Note

The simulations are based on libRadTran using hourly mean global radiation measurements to estimate cloud cover. The simulations were for each hour and the results integrated for the whole day.
