The Totten Glacier in East Antarctica, with an ice volume equivalent to >3.5?m of global sea-level rise, is grounded below sea level and, therefore, vulnerable to ocean forcing. Here…
Space weather forecasting is a very important tool for the space situational awareness to the space objects, the space environment and related threats and risks for manned and non-manned spacecrafts. The global network of ground based multi-directional detectors (GMDN)…
The Global Muon Detector Network (GMDN) was … completed by installing a multi-directional cosmic-ray muon … hodoscope in Kuwait University in March 2006. The GMDN is … currently consisting of four multi-directional muon detectors … located at Nagoya (Japan), Hobart (Australia), Sao Martinho …
A multi-directional telescope for detection of high-energy galactic cosmic rays (GCRs) - muons … was installed in 2001, through an international cooperation between Brazil, Japan and USA, and … operated since then at the Southern Space Observatory - SSO/CRS/INPE - MCT, (29S, 53W)…
We present for the first time hourly variations of the spatial density gradient of 50 GeV cosmic rays within a sample … solar rotation period in 2006. By inversely solving the diffusive flux equation, including the drift…
We have developed a method for determining ICME (Interplanetary coronal mass ejection) geometry from galactic cosmic ray data recorded by the ground-based muon detector network. The … cosmic ray density depression inside the ICME, which is the cause of a Forbush decrease…
We report the first systematic survey of cosmic ray precursors of geomagnetic storms. Our data set comprises the 14 “major” geomagnetic storms (peak Kp >= 8–) identified by Gosling et al. (1990) together with 25 large storms (peak Kp >= 7–) observed from 1992 through 1998.
