sun_daily.spct: Daily solar spectral irradiance (simulated)

In photobiology: Photobiological Calculations

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

sun_daily.data

sun.daily.spct

sun.daily.data

Format

A source_spct object and a data.frame, each with 511 rows and 3 variables

An object of class tbl_df (inherits from tbl, data.frame) with 511 rows and 3 columns.

An object of class source_spct (inherits from generic_spct, tbl_df, tbl, data.frame) with 522 rows and 3 columns.

An object of class tbl_df (inherits from tbl, data.frame) with 511 rows and 3 columns.

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)

Deprecation!

Objects sun.daily.spct and sun.daily.data have been renamed into sun_daily.spct and sun_daily.data, for consistency with other data sets in the package. Please, use the new names for new code.

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.
