EU Horizon 2020 project PAGER started. The kick-off meeting held in Potsdam at GFZ.

The PAGER project will combine models from the Sun to the Earth’s inner magnetosphere + ensembles of physics-based & ML models to make predictions of space weather conditions 1-2 days in advance
In the vicinity of Europa and Ganymede, that respectively have induced and internal magnetic fields, chorus wave power is significantly increased. The observed enhancements are persistent and exceed median values of wave activity by up to 6 orders of magnitude for Ganymede. Produced waves may have a pronounced effect on the acceleration and loss of particles in the Jovian magnetosphere and other astrophysical objects. The generated waves are capable of significantly modifying the energetic particle environment, accelerating particles to very high energies, or producing depletions in phase space density. Observations of Jupiter’s magnetosphere provide a unique opportunity to observe how objects with an internal magnetic field can interact with particles trapped in magnetic fields of larger scale objects.
Update: The hiring process is finished.
Space Environment Modeling Group (https://rbm.epss.ucla.edu/) in the UCLA Department of Earth, Planetary, and Space Sciences is looking for part-time undergraduate student with strong CS background to join our team. It’s a good chance for you to be involved in cutting-edge research, to sharpen your CS skills, and to work with like-minded individuals. You will be paid for your work, and compensation will depend on your experience
The profiles of phase space density (PSD) showed clear deepening minimums consistent with the scattering by electromagnetic ion cyclotron (EMIC) waves . Long-term evolution shows that local minimums in PSD can persist for relatively long times. (more…)
Radial diffusion is one of the dominant physical mechanisms that drives acceleration and loss of the radiation belt electrons, which makes it very important for nowcasting and forecasting space weather models. Comparison of the simulation results with observations showed that the difference between simulations with different radial diffusion parameterization is smaller than the inclusion of local acceleration and pitch angle diffusion.

Accuracy of space weather prediction depends strongly on the quality of the models. A team led by the GFZ German Research Centre for Geosciences demonstrates how errors in the algorithms can lead to wrong predictions. (more…)
A geomagnetic storm on January 17, 2013, provided unique observations that finally resolved a long-standing scientific problem. (more…)
Applied Mathematician Dr. Tatiana Podladchikova was awarded the International Alexander Chizhevsky Medal at the 12th European Space Weather Week, for major results in space weather.
This structure is pretty close to the Earth, which is important because people want to understand the environment where satellites operate. Usually plasma undergoes a number of different instabilities, and waves tend to move from one region in space to another, so everything you see is noisy, very short-lived, and on smaller scales. But this structure seems to be very persistent, highly coherent in space, and was remarkably organized and structured, which we didn’t know could exist to such high degree.
We have replaced our FTP server and restored the original reanalysis files.
Check the FTP, and please feel free to email us if you have any questions.
Version 1.0 is available, and we’ll be uploading a new version some time in the next two weeks with improved errors and GOES data coverage
