R Package Update
photobiologyWavebands pkg
PAR, or photosynthetically active radiation, as defined by McCree (1972) and used almost universaly in plant sciences is a biological spectral weighting function or BSWF that for spectral irradiance in photon based units takes one of two values for the weights: 0 or 1. So for computations of PAR photon irradiance (or PPFD) it is equivalent…
