Photosyntetic active radiation @ 200 cm - 5min average (µmol/m2/sec)

Photosynthetic active radiation (PAR) (wavelengths between 400 and 700 nm) measured on two proximal climate stations at 200 cm above ground as a 5min average (µmol/sec.m2). The double masted climate station is located between Badesø and Langsø at 40 m a.s.l.. The timeseries starts in 2008. Quality control is performed on both datasets from the double mast system. The combined time series is calculated as an average of the 2 sensors, or if data is missing from 1 sensor the other used in conjunction with a regression.
