Scientific paper

The digital ionosonde at Sodankylä Geophysical Observatory, Finland, is performing continuous high time resolution soundings since the beginning of IPY in 2007. During the partial solar eclipse which occurred on first of August, 2008, a stable sporadic E layer was observed with the ionosonde. Using the time development of the recorded echo power of the sporadic E trace at different frequencies as a constraint, we analyse the underlying lower thermospheric and ionospheric D-region characteristics, by applying a detailed coupled ion and neutral chemistry model SIC (Sodankyla Ion Chemistry model), together with modeling of the radio wave propagation and absorption. Use of a simplified ion chemistry model is compared with the use of the SIC model. While the expected effect of the solar eclipse on E-layer critical frequency cannot be seen due to the existence of the sporadic E layer, ionisation in the D-region is consistent with the variation of solar radiation during the eclipse.
