#9 Using STEREO/SDO Data to Model Space Weather

The critical observations from STEREO and SDO will help provide accurate and timely space weather storm warnings, and will aid greatly in our efforts to protect the technologies we have become so dependent in our daily activities. Measurements of coronal mass ejections from the STEREO spacecraft provide vital input for NOAA’s space weather forecasters. Enlil is the first operational physics-based numerical space weather prediction model. Using STEREO input, the model computes the trajectory of solar storms between Sun and Earth, and provides forecasts of geomagnetic storms out to 96 hours.
