Disturbances in LF radio-signals as seismic precursors
radio signals seismicity precursors
2015/9/28
Low Frequency (LF) radio signals lie in the band 30-300 kHz. Monitoring equipment able to measure the electric strength of such signals, at field sites with very low noise levels, were designed and as...
Ionospheric tomography and its applications in radio science and geophysical investigations
ionospheric tomography total electron content ionospheric propagation ionospheric modeling
2015/9/10
The paper reviews recent progress in the development of radio tomographic imaging of the ionized atmosphere,
particularly in relation to the use of the technique to assist in the mitigation of propag...
Atmospheric anomalies over Mt.Etna using GPS signal delays and tomography of radio wave velocities
GPS atmospheric anomalies tropospheric delays tomography of radio wave velocities
2015/9/2
Due to the prominent topography of Mt. Etna, the use of satellite geodetic techniques may significantly suffer from atmospheric heterogeneities. This problem mainly affects the DInSAR technique. To ov...
An overview on preseismic anomalies in LF radio signals revealed in Italy by wavelet analysis
LF radio-waves wavelet seismicity precursors
2015/9/1
Since 1996, the electric field strength of the two broadcasting stations MCO (f=216 kHz, southeast France) and
CZE (f=270 kHz, Czech Republic) has been sampled every ten minutes by a receiver (AS) lo...
COST 296 MIERS: Mitigation of Ionospheric Effects on Radio Systems
Ionospheric physics and propagation COST action
2015/8/28
The COST 296 Action MIERS (Mitigation of Ionospheric Effects on Radio Systems) within the ionospheric community has the objectives, embodied in the Memorandum of Understanding (MoU), to develop an inc...
