SuperDARN

SuperDARN is an international HF radar network designed to measure global-scale magnetospheric convection by observing plasma motion in the Earth’s upper atmosphere. This network consists of more than 20 radars operating on frequencies between 8 and 20 MHz that look into the polar regions of Earth. These radars can measure the position and velocity of charged particles in our ionosphere, the highest layer of the Earth's atmosphere, and provide scientists with information regarding Earth's interaction with the space environment.

SuperDARN是一项国际性的高频率雷达网络，旨在通过观测地球上层大气中的等离子体运动来测量全球尺度磁层对流。该网络由超过20部雷达组成，这些雷达工作在8至20 MHz的频率范围内，并针对地球的极地地区进行观测。这些雷达能够测量我们电离层中带电粒子的位置和速度，并为科学家提供有关地球与空间环境相互作用的信息。
