Data for Sunlight Spectra

Data for the extraterrestrial solar spectral irradiance and ground level solar spectral irradiance and irradiance. In addition data for shade light under vegetation and irradiance time series. Part of the 'r4photobiology' suite, Aphalo P. J. (2015) .

Package 'photobiologySun' contains spectral irradiance and irradiance data for solar radiation at ground level and above the atmosphere. It also conatins data for shade light. It complements other packages in the suite of R packages for photobiology 'r4photobiology'. Spectral data is stored in objects of classes defined in package 'photobiology'.

Please, see the web site R4Photobiology for details on this and other packages available as part of the suite.


photobiologySun 0.4.0

Group reference spectra into a collection. Rebuild all data objects adding metadata. New vignette. First CRAN version.

photobiologySun 0.3.7

Convert vignette to R markdown. Add pkgdown support.

photobiologySun 0.3.6

Update for photobiology 0.9.1, ggspectra 0.1.0 and ggplot2 2.0.0.

photobiologySun 0.3.6

Add irradiance example time-series data.

photobiologySun 0.3.5

Rebuild with photobiology 0.8.5.

photobiologySun 0.3.4

Add gap.mspct data.

photobiologySun 0.3.3

Rebuild with photobiology 0.8.0.

photobiologySun 0.3.2

Added hourly spectral data for August. Updated vignette.

photobiologySun 0.3.1

Added hourly spectral data. Updated vignette with an example of the use of these data.

photobiologySun 0.3.0

Data rebuilt with photobiology 0.6.0

photobiologySun 0.2.1

Updated required version of photobiology package to 0.5.15 Edited the vignette to use new high level functions from photobiologygg 0.2.8

photobiologySun 0.2.0

Updated required version of photobiology package to 0.5.7 Edited the vignette to use new high level functions from photobiologygg 0.2.5

photobiologySun 0.1.4

Updated required version of photobiology package.

photobiologySun 0.1.3

Edited the script to use .spct as name tag for spectra instead of .dt. Rebuilt with current versions of photobiology and MayaCalc packages. Edited the vignette to make use of the new function plot.source.spct() specializing the plot() generic.

photobiologySun 0.1.2

Now spectra are in data.frame and data.table compatible "source.spct" objects.

photobiologySun 0.1.1

Added several standard spectra for extraterrestrial and terrestrial solar spectrum from WMO and ASTM. All dataframes now include both spectral photon irradiance and spectral energy irradiance values.

photobiologySun 0.1.0

Just one example spectrum.
