| Zusammenfassung |
| The ground-based neutron monitors (NMs) record galactic and solar
relativistic cosmic rays which can play a useful key role in space weather
forecasting, as a result of their interaction with interplanetary
disturbances. The Earth's-based neutron monitor network has been used in
order to produce a real-time prediction of space weather phenomena.
Therefore, the Athens Neutron Monitor Data Processing
Center (ANMODAP) takes advantage of this unique multi-directional
device to solve problems concerning the diagnosis and forecasting of space
weather. At this moment there has been a multi-sided use of neutron
monitors. On the one hand, a preliminary alert for ground level enhancements
(GLEs) may be provided due to relativistic solar particles and can be registered
around 20 to 30 min before the arrival of the main part of lower energy
particles responsible for radiation hazard. To make a more reliable
prognosis of these events, real time data from channels of lower energy
particles and X-ray intensity from the GOES satellite are involved in the
analysis. The other possibility is to search in real time for predictors of
geomagnetic storms when they occur simultaneously with Forbush effects,
using hourly, on-line accessible neutron monitor data from the worldwide
network and applying a special method of processing. This chance of
prognosis is only being elaborated and considered here as one of the
possible uses of the Neutron Monitor Network for forecasting the arrival of
interplanetary disturbance to the Earth. The achievements, the processes and
the future results, are discussed in this work. |
