ESR/EISCAT - CLUSTER mode 4

ESR

Large (6 pointing direction) magnetic meridian scan to study region between Longyearbyen and Tromsø in more spatial detail, but with resulting loss of temporal resolution. One other (in L-shell) pointing direction to give convection over Longyearbyen.

  • power profile
  • alternating code E-region (details TBD)
  • longpulse F-region (maximum altitude more important than range resolution) : pulse length TBD
  • 10-s pre-integrations

    • EISCAT

     Fixed low elevation VHF with 5-pointing direction magnetic meridian scan by the UHF, with tristatic points at peak of F-region UHF cycle time same as ESR's and the two scan northward together.
