Photosynthetically Active Radiation (PAR)
Overview
Incident Photosynthetically Active Radiation (PAR) on the Earth’s surface represents a part of the solar radiation spectrum from 0.4 µm to 0.7 µm that is absorbed, transferred and stored within ecosystems. PAR constitutes a crucial input parameter that is used in several terrestrial and aquatic ecosystem productivity models to support climate change studies, both on regional and global scales.
