The dataset is part of the expedition PS106/1 of the Research Vessel POLARSTERN to the Arctic Ocean in 2017.During the ice floe camp (draft period, June 4th-16th 2017) 15 pyranometer stations were deployed over the ice floe covering an area of about 1 Km². Each station measured broadband solar irradiance and temperature at 1Hz resolution.Relative humidity was also measured, however its use it is not recommended due to technical problems of the sensors.Each file contains level and cleanliness flag describing the status of the pyranometer dome per day. The criterion is as follows.Cleanlinessclean =1, drops =2, frozen =3, no observation = 4Levelingleveled =1, partially leveled =2, unleveled =3, no observation =4
