The package documentation web site at https://docs.r4photobiology.info/photobiology/ includes a changelog with information for each release since version 0.1.0.
This release includes enhancements related to the computations of reference evapotranspiration:
Changes from version 0.10.6 the most recent CRAN release, are:
- Add function
ET_ref()for computation of reference
evapotranspiration, implementing the original FAO56 formulation of the Penman-Monteith method as well as modified in 2005 for tall and short vegetation according to ASCE-EWRI. The formulation is that for ET expressed in mm/h, but modified to use as input flux rates in W/m2 and pressures expressed in Pa. - Add function
net_radiation()that computes the long wave net radiation balance if downwelling long wave radiation is available and otherwise estimates it. - Add function
irrad_extraterrestrial()that computes down-welling solar irradiance on a horizontal plane at the top of the atmosphere based on the Sun to Earth distance. - Revise function
sun_angles()to also return the Sun to Earth distance.
NOTE: The updated package is on its way to CRAN.
