photobiologyWavebands 0.5.2

  • Rebuild data objects with ‘photobiology’ (0.11.0)

photobiologyWavebands 0.5.1

CRAN release: 2023-01-07

  • PAR() was previously defined as a wavelength range, which is correct only for computations of photon irradiance. For computation of energy irradiance the correct approach is to use a weighting function based on the energy per photon. This now fixed. The previous behaviour of PAR() can now be obtained with the new function PhR()or by passing an argument to parameter std. This change affects only computations of energy irradiance, and although not code breaking, returned values will vary slightly.
  • PAR() gains definitions of historical interest as well as the recently proposed extended photosynthetically active radiation, ePAR.
  • Plant_bands() now accepts "Sellaro" and "sensoryBroad" as argument for std.
  • Blue() and Green now accept "broad" as argument for std, corresponding to very broad ranges of wavelengths as frequently used in plant sciences.
  • Update UVI() so that it optionally returns integer values as recommended by WWO for communication of UVI to the general public. Default behaviour remains unchanged.
  • Add erythema() as substitute of CIE(), and UV_health_hazard() as substitute for ICNIRP(). The new functions have a std parameter and by default have the same behaviour as the functions they substitute. CIE() and ICNIRP() are deprecated but maintained to ensure backwards compatibility.
  • Updates to documentation.

photobiologyWavebands 0.5.0

CRAN release: 2022-08-15

  • Minor edit to documentation and update of the manual to comply with HTML 5.
  • On bad arguments to parameter std the returned value is no-longer NA (a logical value) but instead a waveband object with its wavelength fields set to NA_real_, as returned by a call to waveband(). This potentially code-breaking change ensures that the class of the returned objects is always the same, and that NA more easily propagates to further computations.

photobiologyWavebands 0.4.5

CRAN release: 2022-01-07

  • Major bug! The definitions UVA1() and UVA2() were swapped.
  • Git repository moved to GitHub.

photobiologyWavebands 0.4.4

CRAN release: 2020-04-28

  • Add NDVI(), normalized difference vegetation index.
  • Update docs for ‘roxygen2’ 7.1.0.

photobiologyWavebands 0.4.3

CRAN release: 2019-03-28

  • Add waveband definitions for non-standard split of the UVA band with constructors UVAsw() and UVAlw().
  • Add two new definitions of far-red as used in remote sensing: “RedEdge20” and “RedEdge40”.
  • Minor updates to documentation.

photobiologyWavebands 0.4.2

CRAN release: 2017-03-20

Add constructors for frequently used infrared bands, and for lists of infrared bands. Add as additional values recognized as argument for parameter std “RS” for wavelength ranges commonly used in remote sensing to the different existing and new waveband constructors. Add constructors for wavelength-range based waveband definitions for the imagers used in Landsat missions 1 to 8 : “LandsatRBV”, “LandsatMSS”, “LandsatTM”, “LandsatETM”, “LandsatOLI”, and “LandsatTIRS”. Add constructor Landsat_bands() returning lists of waveband objects for the different Landsat missions. Update warning messages and error handling in existing constructors. Update Plant_bands() constructor to support CIE’s UVA1 and UVA2 definitions. Update vignette.

photobiologyWavebands 0.4.1

CRAN release: 2016-08-01

Update documentation.

photobiologyWavebands 0.4.0

CRAN release: 2016-02-03

Remove all definitions of ratios. Remove vignette with plots of the wavebands. Remove dependency of vignettes on package ggspectra.

photobiologyWavebands 0.3.4

Use package ggspectra instead of photobiologygg in vignette for compatibility with ggplot2 version 2.

photobiologyWavebands 0.3.3

Minor correction of hinges in definitions to avoid errors at boundaries.

photobiologyWavebands 0.3.2

Added function and waveband constructor for ICNIRP BSWF. Rebuilt data and package with photobiology 0.8.0.

photobiologyWavebands 0.3.1

R_FR_ratio() now uses “Smith10” giving 10 nm bands.

photobiologyWavebands 0.3.0

Rebuilt data and package with photobiology 0.6.0. This required some minor edits to the vignettes.

photobiologyWavebands 0.2.8

Edited the definitions of Red() and Far_red() to include additional wavelength limits as used by other authors.

Updated User Guide.

photobiologyWavebands 0.2.7

Some edits to vignettes.

photobiologyWavebands 0.2.6

Added luminous efficiency functions for human vision, and the constants used in the definition of Lumen. Setlow’s BSWF is now stored as a response.spct object using the same variable names as in the rest of the suite. The Setlow data from TUV has already been converted to energy units, but this was not noticed when this data was added to the package. This bug is now corrected. Updated User Guide with some examples of the calculation of luminous flux in lux from spectral irradiance data. Added plots of the luminous efficiency curves to the Data Plots vignette.

photobiologyWavebands 0.2.5

Updated vignettes.

photobiologyWavebands 0.2.4

Update to documentation and vignettes. UVR8-related data and functions moved to package photobiologyPlants.

photobiologyWavebands 0.2.3

Now all constructors of waveband objects for BSWFs, have formal arguments w.low and w.high, with values earlier in use, now set as defaults.

Added some references to the documentation.

User Guide edited to match current versions of packages photobiology and photobiologygg, as well as to update to to the current version.

photobiologyWavebands 0.2.2

Changed the definition of SWFs functions not to have any intrinsic wavelength limits, and made this limit a new formal argument on the waveband constructor functions, keeping the same defaults. Returned values should remain unchanged. This bit of flexibility is needed as different authors have used different limits for the same BSWFs.

A new formulation for GPAS has been added. The formulation by Micheletti and Piacentini (2002) is used for example in the TUV model (version 5.0). The new waveband constructor is GEN.M().

photobiologyWavebands 0.2.1

Changed the definition of SWFs to not include wavelengths shorter than 280 nm, except for the case of UVR8 absorbance.

photobiologyWavebands 0.2.0

Edits to User Guide for compatibility and rebuilt with photobiology 0.5.1, now required.

photobiologyWavebands 0.1.0

Merge of photobiologyUV and photobiologyVIS packages. Merged and updated the vignettes. Added functions for calculating UV:PAR photon ratios. Added functions for creating some coherent lists of wavebands (e.g. all ISO defined colours).
