Abstract
The Global Ionospheric Flare Detection System (GIFDS) of the DLR consists of a ground-based network of VLF receivers, which provides amplitude and phase measurements of multiple frequency channels ranging from 10 to 100 kHz. One of the main objectives of GIFDS is the immediate and continuous detection of solar flares as a result of their impact on the lower ionosphere. This presentation focuses on changes of the D-region ionosphere using VLF amplitude measurements. On the example of the solar eclipse of 2015, VLF signal propagation was simulated according to the waveguide mode theory with the help of the Long Wavelength Propagation Capability Code (LWPC). Based on an exponential model of D-region electron densities, ionospheric changes in the lower ionosphere can be reconstructed with high correlation coefficients between measured and modelled VLF amplitudes.
