Chiang Mai University operates the "Chang Van" mobile neutron detector, a twin model
of the "Thimon" (Thailand-Hawaii Neutron Monitor). Over the years, we have successfully conducted multiple expeditions aboard icebreaker ships, supported by the Polar Research Institute of China and the Korea Polar Research Institute, to both the Arctic and Antarctic regions as part of the Latitude Survey...
An overview of the Mexico City Cosmic Ray Observatory (MX-CRO), located within University City, UNAM (19°19'47.9"N 99°10'41.6"W) is presented. The MX-CRO includes a 6-NM64 neutron monitor, a muon telescope, a weather station and an electric field monitor. The neutron monitor, its design and electronics, are the main focus of the presentation.
An overview of the space weather events observed by the Neutron Monitor of Mexico City is presented. The detector is located at the Mexico City Cosmic Ray Observatory (MX-CRO) and it has been operating since 1990. The relevance and scope of its data for space weather analysis is discussed.
Thailand's awareness about space weather has grown significantly in the past decade. It is now commonly accepted that space weather, the dynamics of particles, and radiation outside the Earth can significantly affect human activities on Earth. We have looked at the ionospheric response using GNSS observations during geomagnetically quiet and disturbed times and disturbances produced by the...
Ground-level enhancement (GLE) is triggered by GV rigidity solar energetic particles (SEPs). In such high energies (a few hundred MeV/n to a few GeV/n), the characteristic of an SEP events differs from the more common low-energy SEPs at 1 au. We present several numerical studies on how the characteristics of an SEP event depend on parameters of the interplanetary magnetic field (IMF),...
This study presents Monte Carlo simulations using the FLUKA 4-4 package coupled with
the DMPJET model to analyze the response of neutron monitors at the Princess
Sirindhorn Neutron Monitor (PSNM) in Thailand, the South Pole Neutron Monitor, and a
mobile semi-leaded neutron monitor (Changvan) during a latitude survey. The
atmospheric and detector simulations accounted for deadtime...
