[1]我们提出的结果，空间为基础的观测的精灵期间获得的地中海以色列尘埃实验（MEIDEX）精灵活动进行的航天飞机哥伦比亚在其STS-107使命在2003年1月。从21个不同的轨道上总共保存了106小时的有用数据，其中1/5包含闪电。我们从280公里的高度使用校准的多光谱相机以上雷暴在不同的地理位置，主要是在非洲中部，澳大利亚北方和南美洲，也在太平洋和印度洋的精灵成像。在本文中，我们报告的精灵观察范围1600-2000公里的航天飞机，在40-90公里的高度以上的地面。它们的亮度在665 nm滤光片中在0.3-1.7兆瑞利（MR）的范围内，在860 nm滤光片中在1.44-1.7兆瑞利（MR）的范围内。根据观测到的事件的频率和热带雷暴的数量，我们估计热带地区的雪碧率为每分钟几个。
[1] We present the results of space-based observations of sprites obtained during the Mediterranean Israeli Dust Experiment (MEIDEX) sprite campaign conducted on board the space shuttle Columbia during its STS-107 mission in January 2003. A total of ∼6 hours of useful data were saved from 21 different orbits, of which 1/5 contained lightning. We imaged sprites from an altitude of 280 km using a calibrated multispectral camera above thunderstorms in various geographical locations, mainly in central Africa, northern Australia, and South America, and also over the Pacific and Indian Oceans. In this paper we report on sprites observed from ranges 1600–2000 km from the shuttle, at altitudes of 40–90 km above the ground. Their brightness was in the range of 0.3–1.7 mega-Rayleighs (MR) in the 665 nm filter and 1.44–1.7 MR in the 860 nm filter. On the basis of the frequency of observed events and the number of tropical thunderstorms, we estimate the sprite rate in the tropics to be of the order of several per minute.
