| Zusammenfassung |
| Remote sensing of the ionosphere bottom using long wave radio signal
propagation is a still going strong and inexpensive method for continuous
monitoring purposes. We present a propagation model describing the time
development of solar flare effects. Based on monitored amplitude and phase
data from VLF/LF transmitters gained at a mid-latitude site during the
currently increasing solar cycle no. 24 a parameterized electron density
profile is calculated as a function of time and fed into propagation
calculations using the LWPC (Long Wave Propagation Capability). The model
allows to include lower ionosphere recombination and attachment coefficients,
as well as to identify the relevant forcing X-ray wavelength band, and is
intended to be a small step forward to a better understanding of the solar–lower
ionosphere interaction mechanisms within a consistent framework. |
