photobiology — by Pedro J. Aphalo, 2 months ago

Photobiological Calculations

Definitions of classes, methods, operators and functions for use in photobiology and radiation meteorology and climatology. Calculation of effective (weighted) and not-weighted irradiances/doses, fluence rates, transmittance, reflectance, absorptance, absorbance and diverse ratios and other derived quantities from spectral data. Local maxima and minima. Conversion between energy- and photon-based units. Wavelength interpolation. Astronomical calculations related solar angles and day length. Colours and vision. This package is part of the 'r4photobiology' suite, Aphalo P. J. (2015) .

photobiologyWavebands — by Pedro J. Aphalo, 7 months ago

Waveband Definitions for UV, VIS, and IR Radiation

Constructors of waveband objects for commonly used biological spectral weighting functions (BSWFs) and for different wavebands describing named ranges of wavelengths in the ultraviolet (UV), visible (VIS) and infrared (IR) regions of the electromagnetic spectrum. Part of the 'r4photobiology' suite, Aphalo P. J. (2015) .

ggspectra — by Pedro J. Aphalo, 2 months ago

Extensions to 'ggplot2' for Radiation Spectra

Additional annotations, stats, geoms and scales for plotting "light" spectra with 'ggplot2', together with specializations of ggplot() and autoplot() methods for spectral data and waveband definitions stored in objects of classes defined in package 'photobiology'.

photobiologyPlants — by Pedro J. Aphalo, 5 months ago

Plant Photobiology Related Functions and Data

Provides functions for quantifying visible (VIS) and ultraviolet (UV) radiation in relation to the photoreceptors Phytochromes, Cryptochromes, and UVR8 which are present in plants. It also includes data sets on the optical properties of plants. Part of the 'r4photobiology' suite, Aphalo P. J. (2015) .

photobiologyLamps — by Pedro J. Aphalo, 5 months ago

Spectral Irradiance Data for Lamps

Spectral emission data for some frequently used lamps excluding led emitting diodes (LEDs) available as electronic components. Original spectral irradiance data for incandescent-, LED- and discharge lamps are included. They are complemented by data on the effect of temperature on the emission by fluorescent tubes. Part of the 'r4photobiology' suite, Aphalo P. J. (2015) .

photobiologySun — by Pedro J. Aphalo, 7 months ago

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) .

photobiologySensors — by Pedro J. Aphalo, 2 years ago

Spectral Response Data for Light Sensors

Spectral response data for broadband ultraviolet and visible radiation sensors. Different data sources were used: author-supplied data from scientific research papers, sensor-manufacturer supplied data, and published sensor specifications. Part of the 'r4photobiology' suite Aphalo P. J. (2015) .

photobiologyInOut — by Pedro J. Aphalo, 3 months ago

Read Spectral and Logged Data from Foreign Files

Functions for reading, and in some cases writing, foreign files containing spectral data from spectrometers and their associated software, output from daylight simulation models in common use, and some spectral data repositories. As well as functions for exchange of spectral data with other R packages. Part of the 'r4photobiology' suite, Aphalo P. J. (2015) .

photobiologyFilters — by Pedro J. Aphalo, 5 months ago

Spectral Transmittance Data for Filters

Spectral 'transmittance' data for frequently used filters and similar materials.
