The CERESIS earthquake catalogue and database of the Andean Region: background, characteristics and examples of use
historical seismicity CERESIS database South America intensity data points earthquakesource parameters
2015/9/14
The history of earthquakes in South America starts with the coming of the Spanish and Portuguese 玞onquistadores?at the beginning of the 16th century. Their chronicles, and those of local historians, a...
Background electromagnetic noisein the vicinity 1 Hz as a possible indicatorof earthquake-related anomalies
electromagnetic emission temperature Earth surface impedance earthquake precursor 1 Hz frequency range
2015/9/14
Measurements of space-time distributions of the background emissions in the frequency range 0.5-5 Hz and their seasonal and diurnal variations are presented. The analysis of impedance ratio determines...
Fabry–Perot interferometer as a solar background noise suppressor:application to daytime lidar
Lidar Atmosphere Daytime
2015/8/24
Continuous atmospheric probing by a lidar is a requirement for many applications. However, due to high solar background noise during the daytime, lidar operations are mostly restricted to night-time. ...
Background electromagnetic noise characterization: the role of external and internal Earth sources
Radio noise characterization Ionosphere-magnetosphere Background EM noise Crustal/lithospheric EM sources
2015/8/14
The Earth is surrounded by the ionosphere and magnetosphere that can roughly be seen schematically as two concentric shells. These two composed and inhomogeneous structured shells around the Earth sel...
Orographic role in anomalous VHF propagation on the background of impending earthquakes (EQ)
Orography EQ and VHF anomalous propagation Earthquake RRI Terrain features
2015/8/14
The role of orographic factors in modifying atmospheric dynamics on the background of an impending earthquake (EQ) that might lead to propagation of a signal beyond the Line Of Sight (LOS) is examined...
Extending the Similarity Theory for Atmospheric Boundary Layers: Contribution from Background Stratification
Atmospheric boundary layer similarity theory turbulence stratification effects
2009/6/10
The structure of the atmospheric boundary layer has traditionally been described using only surface fluxes and the Coriolis parameter. We review here the proposal of Kitaigorodskii (1988) and Kitaigor...
