TNA to EISCAT Node

EISCAT Scientific Association (EISCAT) conducts upper atmosphere radar measurements, providing data for the research community.

The incoherent scatter radar system (ISR) is distributed on four sites in northern Scandinavia/Svalbard, with the addition of a heating facility and a dynasonde in Tromsø. A next-generation radar system EISCAT_3D is under development and construction.

Areas of access

EISCAT node is open to experiment proposals in the following fields:

• Polar cap dynamics
• Ionospheric phenomena such as aurora, polar mesospheric clouds and summer echoes (PMC and PMSE), sporadic E-layers and naturally enhanced ion-acoustic lines (NEIAL)
• ISR/HF experiments
• Magnetosphere-ionosphere-atmosphere coupling
• Auroral electrodynamics statistical models
• Space environment-atmosphere coupling at the statistical southern edges of the polar vortex and the auroral oval
• Meteoroids, dust particles and near-Earth objects detection experiments
• Ionospheric 3D imaging
