1. 1. WSA-ENLIL + Cone ensemble modeling of an Earth-directed ICME : Comparison with in-situ observations by Solar Orbiter and WIND at L1

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Alberto García Ribas; [2023]
   Keywords : ;

   Abstract : Coronal mass ejections (CMEs) are considered the most energetic phenomenon in the heliosphere. Originated in the solar corona, they are formed by ejected plasma driven by strong magnetic fields. READ MORE

3. 2. Drag based forecast for CME arrival

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Simon Jaklovsky; [2020]
   Keywords : CME; ICME; Halo coronal mass ejections; DBM; DBEM; solar wind; interplanetary medium; shock; space weather forecast; geoeffectivity; solar-terrestrial interaction;

   Abstract :           Coronal Mass Ejections (CMEs) are considered to be one of the most energetic events in the heliosphere. Capable of inducing geomagnetic storms on Earth that can cause damage to electronics, a pillar which the modern society we live in leans heavily upon. READ MORE

4. 3. Comparison of the shock arrival times for Earth-directed ICMEs provided by the WSA-Enlil+Cone model and in-situ observations at L1: A Case Study

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Anita Linnéa Elisabeth Werner; [2016]
   Keywords : CME; ICME; CIR; WSA-Enlil Cone; CCMC; ACE; SAT; St. Patrick; Sun-Earth connection;

   Abstract : A case study which examines the agreement between prediction and data is performed for three, complex interplanetary shocks which were detected at the Sun-Earth Lagrange point L1 and induced moderate to intense geomagnetic storms. We use model output from previous runs of the coupled coronal-heliosphere WSA-Enlil+Cone model, available through the Community Coordinated Modeling Center (CCMC), and in-situ data from the OMNI data set.

5. 4. Spatial-temporal multi-modal visualization of volumetric simulation and in situ satellite data

   University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

   Author : Emil Axelsson; Tomas Forsyth Rosin; [2015]
   Keywords : Datateknik; Datateknik;

   Abstract : This thesis describes the work done by two students from Link¨oping University during a five month stay at Community Coordinated Modelling Center (CCMC) at the National Aeronautics and Space Administration (NASA). The work includes the implementation of algorithms for rendering time-varying volume simulation data from space weather simulations hosted by the CCMC, as well as visualizing photo sequences taken by the Solar Dynamics Observatory (SDO) satellite orbiting Earth.

6. 5. Interactive visualization of space weather data

   University essay from Medie- och Informationsteknik; Tekniska högskolan

   Author : Martin Törnros; [2013]
   Keywords : scientific visualization; volumetric rendering; ray casting in spherical coordinates; space weather; sun; coronal mass ejection; cme; NASA; Datateknik; Datateknik;

   Abstract : This work serves to present the background, approach, and selected results for the initial master thesis and prototyping phase of Open Space, a joint visualization software development project by National Aeronautics and Space Administration (NASA), Linköping University (LiU) and the American Museum of Natural History (AMNH). The thesis report provides a theoretical introduction to heliophysics, modeling of space weather events, volumetric rendering, and an understanding of how these relate in the bigger scope of Open Space.
