The mesosphere rises to 85 kilometers high.

中间层上升到85公里高。

The mesosphere is the third-highest layer of Earth's atmosphere above the stratosphere and the troposphere, which starts at the Earth's surface.

中间层是平流层和对流层之上的地球大气层的第三高层，始于地球。

The plume was the first to have broken through to the " mesosphere" level, or layer, of Earth's atmosphere, the scientists said.

科学家们说，这是第一个突破地球大气层“中间层”的烟柱。

When we get to the mesosphere, which reaches from 85 km above Earth down to 50 km, things don't get much better.

当我们到达从地球上空 85 公里到 50 公里的中间层时，情况并没有好转多少。

" It's the first time we've ever recorded a volcanic plume reaching the mesosphere, " said Simon Proud, a scientist at Oxford and Britain's scientific research center RAL Space.

牛津大学和英国拉尔太空科学研究中心的一位科学家西蒙·普劳德说：“这是我们第一次记录到到达中间层的火山烟柱。”

Proud added that the only other volcanic plume that might have reached the mesosphere might have been released in the eruption in 1883 of Krakatau, a small volcanic island in Indonesia.

普劳德补充说，唯一可能到达中间层的另一股火山柱可能是在1883年印度尼西亚的一个小火山岛喀拉喀托火山爆发时释放出来的。
