The mesosphere rises to 85 kilometers high.

中间层上升85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，始于地球表面。

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.

当我们达从地球上 85 50 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。
