Comparisons of EISCAT and dynasonde ionospheric measurements: simple to moderately structured plasma densities
Read more of: Comparisons of EISCAT and dynasonde ionospheric measurements: simple to moderately structured plasma densitiesPlasma densities obtained from EISCAT’s UHF incoherent scatter system are compared with profiles inverted from the digital ionograms of a co-located dynasonde. Excellent agreement is found for the bottomside ionosphere […]

A large-scale ionospheric depletion by intense radio wave heating
Read more of: A large-scale ionospheric depletion by intense radio wave heatingA large (100 km N/S), stable, smoothly‐structured and significant depletion (15% in number density) of the daytime Tromsø F‐region was produced inadvertently during a Heater polarisation and beam‐forming procedure. We […]
