NASA conducts research on space weather through various missions such as SOHO, STEREO, and ACE to collect data on solar activity. NASA develops models using this data to forecast space weather events and their impacts. NASA provides space weather data, models, and forecasts to support other agencies and protect infrastructure like power grids from geomagnetically induced currents.

37. Level 1 forecasts NASA observations of explosions on the Sun drive modern model calculations. SOHO and STEREO data used. Model output at the Earth used in a statistical model tp provide probabilistic estimate for GIC at individual nodes of the power grid. GIC forecast file is generated. Model propagates the disturbance to the Earth through interplanetary space. Computations carried out at the Space Weather Laboratory. 20 April 3, 2008
38. NASA ACE Lagrange 1 observations used as boundary conditions for magnetospheric model. Model output used to drive geomagnetic induction and GIC code providing GIC at individual nodes of the power grid. GIC forecast file is generated. Magnetospheric model used to model the current flow in the Earth’s upper atmosphere. Computations carried out at the Space Weather Laboratory at GSFC. 21 April 3, 2008
