Further Information

The above calendar shows the previous and near future schedule for all SuperDARN radars. For more information on special times and specific radars chosen to run special time programs, please see the source files at the SuperDARN Scheduling Github. Below are the definitions of the different times.

Common Time:

An interval of concurrent operation of all SuperDARN radars to produce an identical type of data product (e.g. defined by viewing area, and range and time resolution). This must account for a minimum of 50% of time.

Special Time:

An interval of concurrent operation of some or all SuperDARN radars to produce a special data product different from those of Common Time. While the mode of operation of each radar may be different, the purpose of Special Time is to use the network of radars for a coordinated scientific experiment. It is the responsibility of the experimenter to demonstrate to each PI that the associated Radar Control Program (RCP) is suitable for their radar and complies with each radar's transmission licenses. This must account for no more than 25% of time.

Discretionary Time:

An interval when each radar can operate independently for the specific research goals of individual Principal Investigators, Co-Investigators or Guest Investigators. This must account for no more than 30% of time.

The Scheduling Working Group is in charge of creating and distributing the upcoming months schedule, for more information or submission of an experiment request, visit their homepage or speak to the chair Dr. Evan Thomas.

Individual radars can implement different control programs, to see what control program a radar is using on a certain day, see the summary plot page on this site or the daily overviews here.
