Postscript Files:   Ground  Magnetosphere

Spacecraft Footprints and Ground-Based Instruments (upper panels)

• Coordinates are AACGM (altitude adjusted corrected geomagnetic) coordinates.
• The superscript "P" at the end of the name of spacecraft indicates predictive orbit data.
• Footprints of low-altitude spacecraft are shown only in 2 hour plots.
• The geomagnetic field model for mapping is the Tsyganenko 96 (T96) model.
• The altitude of spacecraft footprints is 120 km.
• Input parameters for the T96 model are the solar wind dynamic pressure = 2.1 nPa, IMF By=Bz=0 nT, and Dst=-20 nT (the same as NASA SSCWeb) when OMNI2 data are not available.
• Dash dot lines from the pole indicate midnight meridians at different universal times.
• Light-gray solid fans indicate fields of view of SuperDARN radars at an altitude of 400 km.
• Large black open circles indicate fields of view of all-sky cameras of OMTI, NIPR, THEMIS, etc. at an altitude of ~250 km; small black open circles indicate locations of cameras other than all-sky cameras, such as EMCCD cameras.
• Blue dots indicate the locations of the EISCAT radars.
• Orange and red dots indicate locations of induction and fluxgate magnetometers, respectively.
• Brown dots indicate locations of riometers and/or imaging riomters.
• Light and dark green dots indicate locations of VLF and LF antennas, respectively.

Spacecraft Orbits (lower panels)

• Coordinates are GSM (geocentric solar magnetospheric) coordinates.
• The superscript "P" at the end of the name of spacecraft indicates predictive orbit data.
• Dashed lines indicate the Shue et al. [JGR, 1998] magnetopause model, the Slavin and Holzer [JGR, 1981] bow shock model, and the THEMIS neutral sheet model.
