SuperDARN Collaboration with THEMIS Ray Greenwald, on behalf of the SuperDARN Community JHU/APL THEMIS Workshop December, 2005
SuperDARNNorthern Hemisphere • Orange and red-shaded radar fields are operational. • Mustard and pink radar fields are under develop-ment or planned. • Rankin Inlet will be opera-tional by Spring 2006. • Finland East and Hokkaido may be operational by Fall 2006. • There may be 11 auroral zone and polar cap radars operational by Fall 2006 as well as 2 sub-auroral radars. • Similar, but less extensive network in S. H.
SuperDARN Data Products • Data products include: • Vector electric fields • Vector plasma drifts • Global convection maps • Measurements cover: • Auroral zone • Polar cap • Subauroral regions. • Complementary to: • Satellite measurements • Ground magnetic observations • Ground optical measurements Data from Wallops Radar and TIMED/GUVI
Backscattered power Line-of-sight velocity 30 dB 1000 m/s -1000 m/s Kapuskasing HF radar: April 6, 2000 1714-1716 UT Real-Time and Archival Data
SuperDARN Scheduling Cycle 17 radars to coordinate - scheduling considered 2 months in advance MONTH M MONTH M-3 MONTH M-2 Month M Month M-2 Month M-1 Radar experiments run Shortlist of intervals spanning a subset of conjunction Submitted to the SuperDARN scheduling working group • SuperDARN spacecraft working group • invites proposals of favorable intervals • “darn-space” mailing list • Cluster GBWG mailing list
Cluster/SuperDARN Coordination Hours of “Cluster mode”
Scheduling Approach • Orbit/footprint plots originally intended for SuperDARN scheduling (Jim Wild, Leic. & Gareth Chisham, BAS) • Now feed into EISCAT scheduling (Ian McCrea, RAL) • Uses publicly available data • PGP files • MSP(Cluster)/MSOP(DSP) • Footprint trace using T96 model • PSW=2nPa, DST=0 nT • IMF BY = IMF BZ =0 nT

Cluster orbit and footprint plots can be found via anonymous FTP at... • machine: cluster.ion.le.ac.uk • directory: c1_pgp_orbit_plots • ...which contains the Cluster orbit/footprint plots (Cluster 1 only, 1 gzipped ps file= 1 month). • If you are also interested in considering the corresponding orbit/footprint for the equatorial DoubleStar spacecraft (known as TC1) then the directory "all_pgp_orbit_plots" on the same machine contains new style plots showing DoubleStar and Cluster (1 gzipped ps file= 1 month). Daily jpg plots of the same format can be found in "daily_orbit_plots" (the new style orbit plots in .gif format 1 file = 1 • day) and "daily_footprint_plots" (the new style footprint plots in .gif format 1 file = 1 day). • Suggestions for November 2005 conjunctions by the end of August please! • Best wishes, Jim Wild and Gareth Chisham (SuperDARN spacecraft working • group)
