From September 2015 - October 2019, four spacecraft missions (with 10 satellites total) were taking magnetic field observations throughout the Earth's magnetosphere. These observations are useful for determining the occurrence of plasma waves, which are important drivers of loss and acceleration of energetic particles in the geospace environment. By combining these datasets to identify where plasma waves occur in response to geomagnetic storms, we can determine where and over how much of the magnetosphere these impacts can be expected.
