The SuperDARN Radars operate 24 hours a day, 365 days a year and produce a large volume of data. The data is divided into common, special, and discretionary time periods.
Common time data consists of measurements taken when all of the radars are being operated in the same mode. Special time data consists of measurements taken when the radars are being operated in a different mode. Discretionary time data consists of measurements taken when the radars are operating independently from one another.
The SuperDARN community is keen to encourage collaboration with others and to provide access to the data set.
SuperDARN common time data should be obtained from the Principal Investigator in your country. If you are not from a participating SuperDARN country, contact the Principal Investigator(s) of the radar data in which you are interested. For data taken by a specific radar during discretionary time, contact the appropriate PI for that radar here.
