Scientists are using instruments on the International Space Station to study phenomena in Earth’s ionosphere or upper atmosphere including thunderstorms, lightning, and the more rare Transient Luminous Events (TLEs). TLEs take many forms, including blue jets (discharges that grow upward into the stratosphere from cloud tops) and colorful bursts of energy above storms called Stratospheric/Mesospheric Perturbations resulting from Intense Thunderstorm Electrification or SPRITES. TLEs can disrupt communication systems on the ground and pose a threat to aircraft and spacecraft. Understanding these phenomena could also improve atmospheric models and weather predictions. Because these events occur well above the altitudes of normal lightning and storm clouds, they are difficult to observe from the ground, but are more readily observed from space.
