WSA-Enlil Solar Wind Prediction


WSA-Enlil thumbnail

Product Description:

Animation of the 2-D structure of the solar wind and Coronal Mass Ejections (CMEs) as
they propagate from the Sun to Earth derived from a Magneto-Hydrodynamic model of the
solar wind. When CMEs released by the Sun are detected, storm-prediction runs are made
by including estimated CME parameters in the ambient solar wind model. The model output
provides one to four days advance warning of CME arrival and structures in the solar
wind that create enhanced geomagnetic activity and high levels of radiation belt
electron.


Target Users:
Product users include industries sensitive to strong variations in the geomagnetic
field, such as: electric power, pipeline, drilling, and surveying. Users also include
the satellite industry due to the impacts of enhance radiation belt levels on
satellite systems.
