WebJun 1, 2024 · The density gradients and irregularities were also detected by Swarm and DMSP as in‐situ density structures that disturbed the GPS signals. The irregularities were a substantial fraction (∼10% ... Weblow-density plasma (bubble) nonlinearly rises to the high-altitude region producing plasma density irregularities also in the topside. The bubble wall becomes steep as it rises, and the operation of drift waves and neutral winds further fragment the large-scale irregularities to smaller and smaller-scale sizes.
