Abstract. An easy-to-use model to
evaluate conductivities at high and middle latitudes in the height range 70–100
km is presented. It is based on electron density profiles obtained with the
EISCAT VHF radar during 11 years and on the neutral atmospheric model MSIS95.
The model uses solar zenith angle, geomagnetic activity and season as input
parameters. It was mainly constructed to study the properties of Schumann
resonances that depend on such conductivity profiles.
Key words. Meteorology and
atmospheric dynamics (middle atmospheric dynamics) – Ionosphere (modeling and
forecasting; ionosphere-atmosphere interaction)
