A 10 Hz irradiance dataset from Oldenburg, Germany

Abstract. Three EKO ML-01 photodiode pyranometers are continually recording 0.1 s global horizontal irradiance samples as part of an in-house weather observation system of the Oldenburg Energy Meteorology Group. The sensors are mounted level on a university building rooftop with inter-sensor distances of about 15 m. A bi-weekly maintenance schedule allows for frequent verification of the horizontal orientation and cleaning of the glass dome. The measurement quality was verified manually using additional measurements from a well-established co-located thermopile pyranometer. Here, we publish more than one and a half years worth of data collected between May 1, 2015 and December 31, 2016.
