Long-term trends in f0 F2 over Grahamstown using Neural Networks
Solar activity magnetic activity
2015/9/25
Many authors have claimed to have found long-term trends in f0 F2 , or the lack thereof, for different stations. Such investigations usually involve gross assumptions about the variation of f0 F2 with...
Long-term trends in the ionosphere and upper atmosphere parameters
atmosphere parameters ionosphere
2015/9/14
The first part of the paper is directed to the investigation of the practical importance of possible longterm trends in the F2-layer for ionospheric prediction models. Using observations of about 50 d...
Hydrological influences on long-term gas flow trends at locations in the Vogtland/NW Bohemian seismic region (German-Czech border)
seismo-hydrology gas flow groundwater level mineral springs mofettes
2015/9/2
One of the typical methods for the identification of seismo-hydrological effects is to monitor changes in the free
gas flow throughout springs or mofettes. For several years, the gas flow regime of m...
