Daily PAR from the Arctic Ocean between 1998 and 2014
Instruments were calibrated by the manufacturer before each cruise. All instruments were cleaned on a regular basis and were recording PAR continuously (at 1 to 15 min intervals) throughout the field campaigns, providing detailed diurnal and seasonal variability of incoming light in Arctic.
