dc.description.abstract | The ArcLight observatory provides hourly continuous time series of light regime data (intensity, spectral composition, and photoperiod) from the Arctic, Svalbard at 79° N. Until now, no complete annual time series of biologically relevant light has been provided from the high Arctic due to insufficient sensitivity of commercial light sensors during the Polar Night. We describe a camera system providing all-sky images and the corresponding integrated spectral irradiance (𝐸�PAR) in energy or quanta units, throughout a complete annual cycle. We present hourly–diel–annual dynamics from 2017 to 2020 of irradiance and its relation to weather conditions, sun and moon trajectories. | en_US |
