Community-wide validation of geospace model ground magnetic field perturbation predictions to support model transition to operations
[1] In this paper we continue the community-wide rigorous modern space weather model validation efforts carried out within GEM, CEDAR and SHINE programs. In this particular effort, in coordination among the Community Coordinated Modeling Center (CCMC), NOAA Space Weather Prediction Center (SWPC), modelers, and science community, we focus on studying the models’ capability to reproduce observed ...
متن کاملIntroduction to special section on ‘‘Results of the National Science Foundation Geospace Environment Modeling Inner Magnetosphere/ Storms Assessment Challenge’’
[1] The National Science Foundation sponsors the Geospace Environment Modeling (GEM) program, devoted to understanding the scientific underpinnings for the creation of a Geospace General Circulation Model. The GEM program is organized into finite-length campaigns, one of which is the Inner Magnetosphere/Storms (IM/S) Campaign, which is ending in 2006. The final activity of the IM/S Campaign was...
متن کاملCoordinated studies of the geospace environment using Cluster, satellite and ground-based data: an interim review
A little more than four years after its launch, the first magnetospheric, multi-satellite mission Cluster has already tremendously contributed to our understanding about the coupled solar wind magnetosphere ionosphere system. This is mostly due to its ability, for the first time, to provide instantaneous spatial views of structures in the system, to separate temporal and spatial variations, and...
متن کاملMagnetic field generation from cosmological perturbations.
In this Letter, we discuss the generation of magnetic field from cosmological perturbations. We consider the evolution of three component plasma (electron, proton, and photon) evaluating the collision term between electrons and photons up to the second order. The collision term is shown to induce electric current, which then generates magnetic field. There are three contributions, two of which ...
متن کاملComparing ground magnetic field perturbations from global MHD simulations with magnetometer data for the 10 January 1997 magnetic storm event
[1] A model has been developed to calculate the perturbed magnetic field at various ground-based magnetometer sites using the output of the ionospheric currents from the Lyon-Fedder-Mobarry Global MHD code. The model uses the computed ionospheric currents and the height dependence of the electrojet current above the ground, by evaluating the penetration depth of the precipitating energetic elec...
